By definition, black is the absence of light and color. In the real world, all objects with the possible exception of black holes reflect some light, but objects that appear black are absorbing, rather than reflecting, most wavelengths (colors) of visible light.
A true black will not reflect any light of any colour.
absorbed, which is why the object appears black. The object does not reflect any colors back to our eyes.
A red object appears dark and almost black in green light because red objects absorb green light and do not reflect any light back to our eyes.
An object that absorbs all light appears black, as it does not reflect any light to our eyes.
Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.
A true black will not reflect any light of any colour.
An object which apears black absorbs all colours and reflects none, hence it appears black, black being the absence of colour.
absorbed, which is why the object appears black. The object does not reflect any colors back to our eyes.
Black
A red object appears dark and almost black in green light because red objects absorb green light and do not reflect any light back to our eyes.
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.

it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black
The simple answer is black. However, this is true only if the colour of said object is pure blue; If it has even the slightest tinge of red in it, you will see a very dark shade of red.
An object that appears black reflects very little light, absorbing most of the colors in the visible spectrum. This means that the object does not reflect specific colors, but rather absorbs them all, giving it a black appearance.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
