color relationship

Color, or colour is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra.

Colors

Primary, Secondary and Tertiary Colors

In the RYB (or subtractive) color model, the primary colors are red, yellow and blue.

The three secondary colors (green, orange and purple) are created by mixing two primary colors.

Another six tertiary colors are created by mixing primary and secondary colors.

Types of colors

Tints, Shades, and Tones

These terms are often used incorrectly, although they describe fairly simple color concepts. If a color is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. And if gray is added, the result is a different tone.

some fascinating research in this area which suggests tentative links between color preference, personality and career.Cool colors Colors can be described in terms of temperature, wavelength. The cool colors (blue, green and purple)are of low wavelength and energy and are considered to be restful and quiet. They are associated with sedate mood

states, low arousal, soothing, relaxation and contemplation. selective in responses to stimuli, less distracted by noise detached, cold, reserved, difficulty adapting to new circumstances. Blue is the lowest wavelength colour and is the opposite to red. Experiments have found that blood pressure decreases under blue light and increases under red light. The same applies to speed of respiration, blinking and brain waves.

Warm colors (red, orange yellow) are of high wavelength and high energy. They are active and stimulating. People who like these colors tend to have shorter reaction times, and are more open and responsive to stimuli. They need to have their needs gratified and can be more aggressive. Preference for the color yellow declines with age with less older people preferring yellow.

Bright colors elicit mainly positive emotional associations, while dark, drab colors elicit negative emotional associations - they weaken spirits, morale, health, and may lead to crime, inferiority, and inhibit optimism, inspiration, and success.

Colors and nature

Staff prefer to work in blue or white officesA survey by Create a Wall suggests that British workers prefer to work in blue or white offices to maximise productivity. 22.4% of workers preferring to work in a blue office. Blue creates a calming ambience and research has linked blue rooms with improved cognitive performance. If staff are calm and focused, productivity will increase. White was second most popular (22.1%) - white reflects light around the room, which is ideal if it’s small. White can help to make your room appear bright, vibrant and bigger than it actually is. Light is also important to boost your employees productivity. Studies have highlighted a direct correlation between levels of employee performance and the amount of natural light they are exposed.

Fact

Cultural biasCertain colors have been found to be preferred regardless of age, race, or culture but color preference may be culturally-based: red and blue were the most preferred colors among Americans, but less preferred in other cultures (Choungourian 1968). In the West black is the color associated with funerals but in the East, white is the predominant color at funerals. According to Research at Oxford University desserts served on white plates are perceived to taste sweeter than those served on black plates!

Colors are rich with symbolism. This symbolism can be apparent in how an individual associates colors with things, objects or physical space.

Findings seem to suggest that steering customers away from black cars would make the roads safer, this might not necessarily be the case.

This is because having lots more white cars on the road would mean there was less contrast between vehicles and so make them harder to spot.

Researcher Dr Stuart Newstead said: 'Whilst campaigns to modify vehicle color choice could alter the crash risk for the fleet, color is a much less influential crash risk modifier than behavioral traits such as drink-driving, and speeding.

'It may be possible that simple solutions such as the use of daytime running lights or headlights could effectively negate the elevated risks of higher risk vehicle colors.’

Hypercolor used in fabricSubstances that can change color due to a change in temperature are called thermochromes. There are two types of thermochromes: liquid Crystals (used in mood rings) and leuco dyes (used in Hypercolor T-shirts).The color change of Hypercolor shirts is based on combination of two colors: the color of the dyed fabric, which remained constant, and the color of the thermochromic dye. Droplets of the thermochromic dye mixture are enclosed in transparent microcapsules, a few micrometers in diameter, bound to the fibers of the fabric. Transformation between leuco and colored form of crystal violet lactone in response to varying acidity, which is caused by changing temperatureThe thermochromic droplets are actually a mixture of several chemicals- crystal violet lactone (the color-changing dye itself), benzotriazole (aweak acid), and a quaternary ammonium salt of a fatty acid (myristylammoium oleate) dissolved in 1-dodecanol as solvent. Together, these lead to a reversible chemical reaction in response to temperature change that produces a change of color.At low temperatures, the mixture is a solid. The weak acid forms a colored complex with the leuco dye by causing the lactone ring in the center of the dye molecule to open. At high temperatures, above 24–27 °C, the solvent melts and the ammonium salt dissociates, allowing it to react with the weak acid. This reaction increases the pH, which leads to closing of the lactone ring of the dye to convert it to its colorless (leuco) form.Therefore, at the low temperature the color of the shirt is the combination of the color of the encapsulated colored dye with the color of the dyed fabric, while at higher temperatures the capsules become colorless and the color of the fabric prevails.

Automotive paint system that changes colors with changes in temperature. Now it is not talked about something that looks like different colors at different angles, it is talking about a paint that can go from black to white, red to yellow, Purple to green, or just about any other combination you can think of. The paint can be mixed with pearls, metal flakes, micro-sequins, and most other custom paint additives. Paints that have the property of going from a colored state to clear that allows to hide and reveal graphics under the paint. For example a Viper painted on the hood of a Dodge Viper that would only appear when the engine got the hood hot, or real ghost flames that are invisible until activated. It can engineer the paint to change colors at any temperature between 0 F to 150 F. Please note that hidden graphics must be incorporated in the original design of the graphics. Another way to incorporate the graphics is that almost any color go from for instance black to that color, so you would paint the graphic with colors while hot and when they cool all of the colors go black, but this can be done with any of colors. Another option is to match a graphic color to the cold color of the paint so that when it heats the rest of the background changes color leaving only the graphic.

Well previously seen paintwork that could change color with water application, that was done by the change in temperature.This changes paint color by adjusting the voltage of an electrical current sent through the vehicle’s bodywork. With the introduction of a new technology using ‘paramagnetic’ paint coating, the choice won’t be set in stone the moment the car rolls off the production line. In fact, the concept is to allow owners to change the paintjob whenever they see fit – whether that be in the car park or at the lights.                                                                                                                                 Technology works by running a current through a special polymer applied to the vehicle before painting. This polymer contains particles of ‘paramagnetic’ iron oxide. With the application of an electric current, the spacing of the oxide’s crystals is adjusted, affecting their level of light reflection and thus our color perception.                                                                                                                                                      Cars, being rather conductive metal objects, are therefore the perfect medium for such a technology, with the small current maintaining a particular color. However, with no current, such as when the car is turned off, the paint would return to its default color of white,

This is a video of a Nissan Skyline R33 that was coated with heat sensitive paint by UK bodyshop Auto Kandy changing color as cold (or hot?) water is poured on it. I wish my car did that. Of course I wish my car did a lot of things, including not get broken into so often. The last person who broke in stole my eyeglasses, a McDonald's bag full of other fast food trash, and a bookbag of dirty laundry. So if you see anybody in the area wearing an unwashed Transformers t-shirt I want you to notify the police. No -- I want you to notify me, and I'll vigilante justice them myself. "But what if it's the wrong person?" Relax, I'm gonna make it look like an accident. "Who trips and falls on a ninja sword covered with your fingerprints?" It could happen!Hit the jump and watch the Hypercolor car in action.

White and yellow cars had a slightly lower risk of being passively involved in a crash. Silver cars were 50% less likely than white cars to be involved in a crash. Lighter or brighter-colored cars will keep them more visible and thus make them safer on the road.

Note:- None of the colors tested were statistically safer than white, though some had equal relative crash risk. but other factors were more influential on crash risk and for drivers to be aware of this
