Why does the shade of Black, absorb and diminish all other colors?

Question

What is the science behind the shade of Black?

Answer 1

black is the absence of color as to white is the combination of all colors. in the same way that white reflects light because of its components, black attracts or absorbs light because it has no color component at all and it has nothing to refract light.

Answer 2

A Black engine should run cooler than white. When people say 'black absorbs more heat than white' they making an implicit assumption, assumption which is valid, for example on a sunny winter day.

To put it very simply:

Black paint is like open door. On a cold day it will let the energy from the sun be absorbed easily (by a cold object). White paint is like (partly) closed door for the heat.

Because the engine is hotter than environment, open door will allow the heat to leave - and engine will run cooler.

To put it into a mote technical language:

Black paint promotes equlibration, white will slow it down.


In a special case (of hot sun, cold box or house) the general rule is reduced to : cold box will absorb more heat when painted black.

Answer 3

It's been told to me that blk is the absence of color. Blk is a neutral color it doesn't diminish a color at all just makes it darker. So even if the color mixed with blk takes on a blk shade the color is still there. Neutral colors are blk, and white, there used to shade or tint colors.
