Reflection of 100% of incident light at all wavelengths is a form of uniform reflectance, so white is an achromatic color, meaning a color without hue. [35] [36] The color stimulus produced by the perfect diffuser is usually considered to be an achromatic stimulus for all illuminants, except for those whose light sources appear to be highly ...
A color term (or color name) is a word or phrase that refers to a specific color. The color term may refer to human perception of that color (which is affected by visual context) which is usually defined according to the Munsell color system, or to an underlying physical property (such as a specific wavelength of visible light).
There are many color perceptions that by definition cannot be pure spectral colors due to desaturation or because they are purples (mixtures of red and violet light, from opposite ends of the spectrum). Some examples of necessarily non-spectral colors are the achromatic colors (black, gray, and white) and colors such as pink, tan, and magenta.
The web colors white and white smoke are achromatic colors. A chromatic shade of white is a white color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of white.
Light skin is a human skin color that has a low level of eumelanin pigmentation as an adaptation to environments of low UV radiation. [1] [2] Due to migrations of people in recent centuries, light-skinned populations today are found all over the world.

But for us it was simple: the color of the sky, the color of the heavens, what lies in front of us.” If 1999 was about embracing the unknown and engaging some blue-sky thinking, Pantone ...
To promote uniformity of practice in the evaluation of whiteness of surface colors, it is recommended that the formulæ for whiteness, W 2 or W 10, and for tint, T w,2 or T w,10, given below, be used for comparisons of the whiteness of samples evaluated for CIE standard illuminant D65. The application of the formulae is restricted to samples ...
