There are many answers to the question you ask, this site explains how and why:
Color perception is also affected by the environment in which the color is seen. Daylight is rich in bluish tones because of the presence of ultraviolet radiation. Incandescent light and candle light are rich in yellow tones. The perception of any color requires the presence of light.
Our perception of color changes as the light source is changed or when the surface that reflects the light is stained or coated with a pigment.
What we commonly think of as color refers to the chromatic colors. These colors relate to the spectrum that can be seen in a rainbow. The neutral colors of black, white and grays are not part of these colors and are referred to as achromatic colors

If Earth had no atmosphere what color would formerly red or gold objects be?
They would be red or gold. The presence or absence of an atmosphere has no effect on what wavelength/frequency of light the object emits (except in very specially engineered circumstances having to do with reactions and not simply the presence itself).
If there was no light on earth would color exist?
Correct. No light, no color.
Can you die a light color item that has been bleached to make it a darker color?

Is the color black a natural color?
Technically speaking, black is not a color at all. Color is the way we perceive light of a given frequency; if it has a wavelength that is, say, 510 nanometers, then we perceive green light. Black, however, is an absence of light. Therefore, black is not a color at all, rather, it is an absence of color. Unless you are speaking of subtractive colors - then black is the presence of all color and white is the absence of all color. Additive color is light - subtractive color is the color that light bouncing from an object creates.

Is white the absence of color or the presence of all color?
Clear light is the presence of all colors. You can separate them by wavelength using a prism and get a spectrum (rainbow). When you're talking pigment, it's the absence. You can't mix all your paints together and get white.
Does iodine color rocks a red color?
No, iodine does not colour rocks red. However, a presence of chromium in rocks emits a red colour when exposed to yellow/green light.
Is white the absence of all color or the presence of all color?
Clear light is the presence of all colors. You can separate them by wavelength using a prism and get a spectrum (rainbow). When you're talking pigment, it's the absence. You can't mix all your paints together and get white.
Why is no color reflected from black color?
If you are talking about 'subtractive' color - like the color of your pants or a chair or a car then it is because black is the presence of all colors and the color reflected back at your eye is literally the combination of them all. It isn't that no color is reflected back - it is that all of them are and so the effect that we see, in a prism, let's say, is prevented because the light - as it reflects upon our eyes - isn't able to separate any one of the colors from the rest. In 'additive' colors - like the colors on your TV screen or on your computer monitor - black is the absence of all color and white is the presence of all color. Additive color is created with light itself. If there is no light - there is no color - and that is where you find a truly "color-free" black .
