What happens when white light is shone onto a coloured object?

What colour will a white object appear if only red light was shone on it?
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.
What color appears when lights of any 2 primary colors are shone on a white object?
When lights of any two primary colors are shone on a white object, the object will appear to be a secondary color that is created by mixing those two primary colors together. For example, red and blue light will make the object appear purple, red and green light will appear yellow, and blue and green light will appear cyan.
What colour will an object appear to be under white light if it reflects all the colours of light?
The object will appear white. When an object reflects all colors of light equally, it will appear white because white light is a combination of all colors in the visible spectrum.
What happens to a red object when light is shone on to it?
