White is the colour in 2016

Actually if you had ever mixed paint you would know that white has yellows and greens and reds and even black in it. None of the whites you see are pure white.

How true and why when you put white light through a prism it breaks down to all the colors of the rainbow as white is all colors combined!
In the visible spectrum, white reflects light and is a presence of all colors, but black absorbs light and is an absence of color. Black can be defined as the visual impression experienced when no visible light reaches the eye and why when I ride a black scoot no one can see me and the ones who can are out to kill me.

From a computer standpoint, pure white has no color until you start adding other colors including grays. The top (North pole) of the HSL Color Diamond is pure white, the bottom (South pole) is pure black. The vertical line between both poles are pure gray scale. The outermost circumference (equator) is pure color. Everything else is a mixture.

This 3D model is great for doing color conversions.

"Visible light, radio waves, x-rays and other types of radiation are all part of the electromagnetic spectrum. Visible light is electromagnetic radiation with wavelengths ranging from roughly 400 and 700 nanometers. In physics, a color is visible light with a specific wavelength. Black and white are not colors because they do not have specific wavelengths. Instead, white light contains all wavelengths of visible light. Black, on the other hand, is the absence of visible light.

Definitions of Black and White
The correspondence of a color to a specific wavelength is called spectral color. White and black are excluded from this definition because they do not have specific wavelengths. White is not defined as a color because it is the sum of all possible colors. Black is not defined as a color because it is the absence of light, and therefore color. In the visual art world, white and black may sometimes be defined as distinct colors. This is different from the concept of spectral color in physics.

Where Does White Light Come From?
When objects generate extreme amounts of heat, they produce radiation across the entire electromagnetic spectrum, including visible light. This process is called blackbody radiation. A blackbody is a theoretical object that absorbs all radiation. Consequently, it heats up and then emits radiation across all wavelengths. As real world objects become hotter, their behavior approaches that of a blackbody. This is why the light from the sun includes all colors of visible light; it is so hot that it behaves like a blackbody.

How Do We Experience Color?
When we see color, we experience light of that wavelength reflecting off an object or emitting from it. For example, when light from the sun shines on your blue t-shirt, the t-shirt absorbs all of the light other than the blue light. The t-shirt reflects the blue light and some of it reaches your eyes. Black is the absorption of all visible light. This is also why your black t-shirt is hot on a sunny day. All of the colors of visible light are absorbed into a black object, heating it up."
