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 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 is the wavelenth of black color?
Black is not actually a colour associated with a unique wavelength of light. Black objects absorb nearly all the light at wavelengths our eyes can detect. When we look at something black we are actually seeing 'no light' (or very little compared to the surroundings).White light is the exact opposite; white objects hardly absorb any light. When we look at white objects, our eyes take in light at all wavelengths and we interpret this as the 'colour' white.Visible light wavelength range: 390 to 750 nm (there are 1,000,000 nm in 1 mm)Any light outside this range cannot be seen by humans and could be called 'black'
Does a black object get warmer in the sunlight than a white object?
Most of sunlight is in the visible range of the spectrum. A black object by definition absorbs all visible light, while a white object reflects all visible light. The black object absorbs most of the energy from sunlight, turning it into heat.

Black is just a "color" made by a surface chemical absorbing all light, therefore meaning that if there is no light, objects will look black.
