Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black.
It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.

What colour will a green object look like in blue light?
A green object will appear dark or black under blue light because it does not reflect blue light well. Green objects absorb blue light, resulting in little to no reflection of this color.
Why does a blue object look black in red light?
Blue objects absorb most of the red light that hits them, reflecting very little red light back to our eyes. This causes the object to appear black in red light because red light is the only color that can reveal the object's true color.
What colour does blue look under a red light?
Under a red light, blue would appear dark or black because red light is absorbed by objects that are not red. Since blue is not a color in the red light spectrum, it cannot reflect or be seen under red light.
What would a red object look like shone onto a blue light?
Red and blue are at opposite ends of the visible light spectrum, red being of low frequency, and blue being of high frequency. Sunlight contains frequencies across the whole frequency range, which appears white. An object that appears white reflects all frequencies. A red object appears red because it reflects red (low frequency) light, and absorbs all other colours. Blue light contains only high frequencies. If you are in a darkened room, lit only by blue light, white objects will appear blue because they are reflecting the blue light, and no other frequency is available. But a red object absorbs high-frequency (blue) light, and since this is the only light in the room, it does not reflect any light. Objects that do not reflect any light appear black. Some objects appear black even in sunlight, because they absorb all frequencies and do not reflect any. So to answer the question, when you have a red object that is lit only by blue light, it will appear black.
What color will a cyan object look under red light?
A cyan object will appear black under red light because red light is absorbed by cyan objects. Cyan is a combination of green and blue light, so when only red light is present, there is no light for the cyan object to reflect or absorb.
What colour will a green object look like in blue light?

black
Why does a blue hat look black when it is in a dark room?
A blue hat looks black in a dark room because the lack of light prevents our eyes from perceiving its color. Colors are determined by the wavelengths of light that objects reflect; without sufficient light, the hat does not reflect enough blue wavelengths for our eyes to detect. Instead, it appears as a shade of black or gray, as the limited light makes it difficult to distinguish its true color.

A cyan object will appear black under red light because red light is absorbed by cyan objects. Cyan is a combination of green and blue light, so when only red light is present, there is no light for the cyan object to reflect or absorb.
