...traditional color wheel used by painters, violet and purple are both placed between red and blue. Purple occupies the space closer to red, between crimson and violet.[3] Violet is closer to blue, and is usually less intense and bright than purple. While the two colors do look similar, from the point of view of optics there are important differences. Violet is a spectral, or real color – it occupies its own place at the end of the spectrum of light, and it has its own wavelength (approximately 380–420 nm). It was one of the colors of the spectrum first identified by Isaac Newton in 1672, whereas purple is simply a combination of two colors, red and blue. There is no such thing as the "wavelength of purple light"; it only exists as a combination.[12] [13] Pure violet cannot be accurately reproduced by the Red-Green-Blue (RGB) color system, the method used to create colors on a television screen or computer display. It is approximated by mixing blue light at high intensity with less intense red light on a black screen. The resulting color has the same hue but a lower saturation than pure violet. One curious psychophysical difference between purple and violet is their appearance with an increase in luminance (apparent brightness). Violet, as it brightens, looks more and more blue. The same effect does not happen with purple. This is the result of what is known as the Bezold–Brücke shift. While the scientific definitions of violet and purple are clear, the cultural definitions are more...

... NINHYDRIN TEST To 4mL of the solution which should be at neutral pH add 1mL of 0.1% freshly prepared ninhydrin solution. Mix the contents and boil for a couple of minutes. Allow to cool | Violet or purple | The ninhydrin test is answered by amino acids and proteins. The formation of a complex called Rheumann’s purple due to condensation of two molecules of nin-hydrin with one molecule of ammonia from amino acid is responsible for the violet color. The -amino group is the reactive group | XANTHOPROTEIC REACTION To 5mL of the solution add 1mL of conc. HNO3. Boil the contents. After cooling ad excess 40% NaOH | On adding acid, yellow color will be noticed. When NaOH is added deep orange color will develop | The yellow color is due to the nitro derivatives of the aromatic amino acids present in the protein. The sodium salts of nitro derivatives are orange in color. | GLYOXYLIC REACTION FOR TRYPTOPHAN (Hopkins-Cole test) Add 2mL of glacial acetic acid to 2mL of the test solution. Then about 2mL of conc.

...The Newly Discovered Purple Chubby Amphibian For decades scientist have tried finding a species that once shared the same land when dinosaurs still crawled on this Earth. To scientist surprise, they recently made an unusual discovery of a new species of frogs. The strange looking new amphibian is known to be a sole surviving member of amphibians that evolved more than 130 million years ago. Scientist calls this species discovery as a ‘once in a century find’ because of it’s belonging to an ancient group of amphibians that once shared the same land with dinosaurs. Formally discovered in 2003, the poignous frog, also known as the “Purple Frog”, has been the talk of all scientist discoveries because of its comic features and behaviors. Although this new species has recently been discovered with highly distinctive and comical appearances, its behaviors adaptive values benefit the amphibian by increasing its total fitness. However scientists might now be able to research this rare species because it is slowly decreasing in population. The purple frog has a sidesplitting appearance with a distinctive habitat in an unusual range of geographical location. This new species of frog can be described as a typical frog at first glance but as you pay closer attention you notice its distinctive appearances compared to other species of frogs. The body has a similar shape like most frogs yet it has a plump bloated body shape with short fore and hind limbs that end in webbed feet with rounded...

...The Store The store that I performed my research on was Big Lots. It has a boy and girl’s aisle as well as a baby aisle that has a very small section of semi-neutral toys. In the girls aisle I found dress-up (Disney princess, monster high and some tutu’s, as well as some generic dress up items), kitchen (pots, pans, aprons and cooking items), baby dolls, and Barbie dolls. All of the packaging for the girls’ toys had very little red, with some white, and yellow, as well as different shades of blue and green but nothing within the dark scale of these colors. Some had black but very little. The majority of the colors were found to be different shades of purple, and pink. All the colors seemed to be themed towards fun and bright. The girls’ toys could all be categorized as either dress-up, playing kitchen or playing with pretend make-up. There were baby dolls that came with bottles and “fresh” diapers for changing. All the toys seemed to be stereotypical for a girl to learn what to do when she grew-up i.e. cooking, cleaning and taking care of a baby/children. Upon examining the isle containing “boys’ toys”, I encountered super heroes, building toys, play guns from pistol to long barrel riffles, different kinds of vehicles from sports cars to construction working trucks, as well as transformers and motorcycles. Career themed toys could also be found ranging from muscle men and law enforcement to firefighters. All of the packaging for the boy’s toys had some white, yellow...

...ʘ In the Pacific Ocean there is an island composed by two mountains. It is as if someone had placed together two big handfuls of earth and stones in the heart of the sea. The bigger one is called Sadness and the smaller one Joy. ʘ Mythology tells us that many centuries ago Joy was larger and higher than Sadness, but, due to an earthquake, part of it fell in the sea, shaping the mountain the way we find it today. No one knows if that is really the truth. ʘ ʘ The fact is that where those two geological accidents meet live a girl named Aletheia and her grandmother. Aletheia and her grandma are like the mountains: two persons who are always together. ʘ Today the girl is shorter and smaller than her grandmother; but some day, nobody knows when, Aletheia will wake and she will be taller than her grandma. Aletheia is going to grow up and I think that when this day comes, they will still be together, just like the mountains of the island. One day this girl asked: “Grandma, who made the world?”. To what her grandmother replied, “God”. - “All of it?”. - “Yes, all of it”. - “By himself?”. - “Yes”. ʘ Aletheia left the room with that conversation on her mind. She was not convinced. She thought about this for a few days. In order to digest her thoughts she went for a walk through the island. Alone she thought. Aloud she though and she began to share her thoughts with whatever crossed her way: leaves, trees, stones, ants, crickets, etc. Had God created the...

...Based on my observation, marijuana leaves exhibits a warty appearance due to the presence of non glandular hairs which at their base contains a spheriodal cystollith of calcium carbonate while on the other sample of marijuana seeds I observed the lacy and hair like. During the Chemical Test of the Fast Blue Salt or FBS Test on the Marijuana seeds, hashish cake and hashish candy I observed that there was a reaction on the test conducted due to the appearance of purple color or violet. On the Marquis test conducted for Morphine, Shabu and Ephedrine there were reaction with the two sample wherein the morphine turned to purple, shabu became orange and lately turned to red dark brown in color while the Ephedrine had no reaction at all. On the Simmon’s test, the color of shabu became blue in color. On the other test in Chen Kao 123, the Ephedrine has a reaction and the color of the sample became purple. The last examination conducted was the Benzidine test- to test whether the stain is blood or not. A stain sample rub with a filter paper and added with 1-2 drops of Benzidine Reagent and 1-2 drops of hydrogen peroxide on the filter paper, instant blue color indicates the presence of blood. CONCLUSION: Based on my observation of the chemical examination or test of prohibited drugs, therefore I conclude that the Marijuana leaves and marijuana seeds are not the same in characteristics. In the chemical test conducted, all the samples reacted...

We can see this through the curve on our graph; our readings from the colourimeter showed that light absorption decreased as the temperature increased, meaning that the solution was more concentrated due to more of the pigmented substance from the beetroot vacuole leaking through the destroyed beetroot membrane. This was also evident through observation of the different solutions of water (as the temperature of water increased, the extent of pigmentation of the water increased). For 20oC, we obtained a reading of .886, which decreased to .238 by 40oC, and eventually to .010...

So as we sat in the living room by ourselves, our host missing in action, same for the hors d’oeuvres. We introduced ourselves and talked among ourselves. After about 30 mins or so we could smell something that was a mix of cooked cabbage and seafood. Our host finally arrived and led us to the table where we were met by a hot steaming bowl with a purplish colored liquid was inside. There was a plate of stale crackers that was passed around to eat with the soup. In the soup there was: undercooked carrots of different sizes, purple cabbage (that’s where the purple color came from), overcooked pasta, corn, onions, potatoes different sizes, and over cooked scallops, shrimp and squid. Like the characters in the story while at the first dinner “we ate in perfect silence, first in shock, then in amazement.” That was the main course. For desert we had pudding cups.

...Rogelyn Mckoy 4/24/13 The History of Color: How people in ancient times created color for their garments. Greek philosophers Democritus and Aristotle and Roman writers Plinythe Elder and Vitruvius described and recorded processes to create fabric dyes. Blues and purples were known as vat dyes. Indingo and woad (a European flowering herb of the mustard family) were used to make blue dyes. These plants required lengthy absorption in an alkaline solution of ash, lime, or urine, which turned them into a water-soluble salt. The fabric was left to air dry and the oxidation made the blue color fast. Tyrian, or royal, purple came from the mucous gland of the murex, a mollusk (invertebrate). A pound of dye required four million mollusks which was a time consuming process. Only the rich, such as the reigning emperor or monarch could afford this shade. Reds were mordant dyes (sarcastic/biting dyes). They required the use of a fixative to create an insoluble color that would remain true. Henna a shrub and madder, a root, were mixed with alum (a sulphate of aluminum and potassium) to render a color family way less intense than the red we know today. A species of female scale insect, kermes was used by the Egyptians and produced a more vivid/intense red. Colors in the yellow family were the least complicated. They were direct dyes, produced with little effort. Weld, the seeds, stems, and leaves of Dyer’s Rocket; and safflower, petals from Dyer’s Thistle, were used to create...

Looking at the new product costs per unit (using ABC) the cost per unit for each product is much different then found under traditional. The cost per unit found under the ABC method was different than what the unit price for each product was being sold for. For blue and black pens the company was making a profit on each pen there were selling (comparing $1.18 product cost for blue and $1.16 for black which were each being sold for 1.50). Red pens cost $2.23 each to make and were being sold for 1.55 each which resulted in a loss. Purple pens were losing the company even more money with costing 4.95 to produce but were only being sold for 1.65 per pen. Under further calculations using the ABC method it was found that blue was the most profitable followed by Black, but that Red and purple were causing the company to lose money, Red was losing the most in dollars with around $6000 while purple was losing a little over $3300. The profit margin was also different than what the traditional product costing found. ABC revealed that Blue and Black pens were actually more profitable than what the company originally thought, but...

...body style of Toyota Celica that came out in 2000. My husband wasn’t so sure. So we looked at Mustangs, Acuras, Eclipses, etc. The Mustang we ruled out because it wasn’t the same if you couldn’t get a Salleen or Rousch package and they were just too expensive. The Eclipse interior was lacking in creature comforts and the Acura was just too boring for me. We finally went to test drive a Celica and it was everything I wanted except it was bright red. (I read the statistics – I know better than to buy a red sports car). By this time it is getting late in the year and the 2003 models were coming out. We went in to a showroom to look at the new Celica colors and they had one in the show room in this light blue that looked almost purple on the edges in the lights. It was like one of those moments in the movies when a spotlight shines down on exactly what you have been looking for. My husband took one look at it and was like “Maybe you are right. Maybe we should get a Celica – in this color.” Now since that color was brand new that meant that a used Celica was out. I looked online to see what I could get the car for through my credit union’s car buying service (my parents got an incredible deal this way) but they didn’t have the new blue color so I had to use the 2002 version of blue for the pricing, but I felt like I at least had something. Part 2: The negotiation Now that we had decided on exactly what we wanted – 2003 Celica, leather interior (only one...

...the road continues into the horizon and faintly disappears in the distance, brings a good effect to the photo because it can make you feel as if you are standing where Cody Duncan was stood. The use of the yellow and white lines going down the centre of the road in the picture give off a symmetrical effect because they are right through the centre of the picture and the scenery on each side is very similar. The road seems flat and smooth which I think also makes the photograph seem calming and deserted. I like the way that the road takes up most of the photo but then disappears into the mountains, which then seem like the main part of the photo. I like the colours that are shown in the mountains, they are cold colours such as blues dusty purples and murky greys and where the sun is shining onto it, it shows pale pinks and yellows.

Besides, the a and b which represents the distance travelled by pigment and distance travelled by solvent were measured and recorded in the table. The Rf value was then calculated by using the formula ab. A= distance moved by the pigment from its original position B= distance moved by solvent from the same position. *Round Rf values to 2 decimal places CONCLUSION: We used paper chromatography to separate the pigments found in spinach. Since plants use several different pigments to capture light energy for the light dependent reaction in photosynthesis, we expected that we would see several different bands of pigments on our chromatography paper. As the data in Table 1 indicates, we obtained four bands of different pigments from the spinach leaf: yellow- brown, light green, green, and yellow. The bands moved different distances up the chromatography paper, and were of different widths. According to the data, our hypothesis was correct. Different types of pigments are present in plants. The distances traveled by the pigments can indicate how big...

Her walk was crooked, and she was bent over and very tense, like she was in a lot of pain. As I was looking at her and trying to understand what might be wrong, suddenly the mother clenched her chest with her hand and fell lifelessly to the ground. Her daughter, who was no more than 5 years old, cried out a screeching “MOMMY!” Startled by this little girl’s scream, all of the other kids and parents who were nearby whipped their heads around and ran towards the mother. She was now laying on the ground her eyes closed, her face was pale and her lips a dark purple color, and her limbs were twisted and...
