What is colour?
We perceive color just as we perceive taste. When we eat, our taste buds sense four attributes: sweet, salty, sour and bitter. Point at the foods below and distinguish their different taste attributes.
The eye sees the colour of an object as white light is shone upon the surface of an object, which then reflects some colours and absorbs others. It is the reflected light – or wavelength, that is picked up by the eye. Therefore a strawberry is reflecting red light and absorbing all the other colours.
Within the eye, the retina contains receptors called rods and cones. The rods react to brightness, whilst the cones react to colour wavelengths. There are three types of cone; red, green and blue. Each colour has a different wavelength; blues, greens and violets have shorter wavelengths and reds, oranges and yellows have longer wavelengths. When coloured wavelengths fall on the retina, the nervous system and the brain interpret the signals as colour.
A color wheel is disk-shaped and divided equally into 12 sections, each displaying a different color according to its “pigment” values.
All colors arise from the three primary colors: red, blue and yellow. These colors are primary because you cannot make them by mixing other colors together. They are represented on the color wheel at equidistant positions, forming a triangle.
Mixing equal values of any two primary colors together creates the secondary colors of violet, orange and green. Since violet is a combination of equal amounts of blue and red, it lies halfway between those two colors on the color wheel. Orange lies halfway between red and yellow, and green between yellow and blue. The secondary colors form another triangle.
Below are the most widely used terms for describing color
Spectrum: All the possible colors in a color space.
Hue: This defines the specific location on a color wheel or in the color spectrum. If you were to select a red area in the color spectrum, you have chosen a red hue.
Tint: This is the process of adding white or light to a color.
Tone: This is the process of adding grey to a color.
Shade: This is the process of adding black to a color.
Value: This describes the range from dark to light, a Blue hue could be shown at varying values. It could vary from light to dark, where the dark would be a traditional Blue color, and the light would be a very powder blue.
Saturation: This defines the intensity of the color, and can sometimes actually be referred to as intensity.
Muted: When a person is describing muted colors, they are often referring to colors that have low saturation, or colors that they deem to be of low intensity.
Contrast: This is probably most important when trying to determine the readability of the design. You want to have high contrast color choices for your text areas, where the separation between two colors on the spectrum is high enough to allow for an easy read. If you were to put a purple color on a turquoise background for instance, the readability would be effected negatively.
