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 colour will a cyan object appear if only magenta light was shone on it?
A cyan object will appear black when only magenta light is shone on it. Cyan objects absorb magenta light, so no light is being reflected back to our eyes, causing the object to appear black.
What colour will a yellow object appear if only Red light is shone on it?
The yellow object will appear dark because it reflects yellow light, which is a combination of red and green light. Since only red light is being shone on it, the object will not reflect any light and will appear black.
What colour will a Green object appear if only Blue light is shone on it?
The green object will appear black because it will not reflect any of the blue light shone on it. Green objects primarily absorb blue light, so without any green or red light present, the object will appear dark.
What colour will a green object be if only blue light was shone on it?
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
If a red light is shone on a green object what would the colour be?
The red light would be absorbed by the green object and the object would appear dark. The green object reflects green light and absorbs other colors.

What colour would a white object be if a blue light shone on it?
blue
What color would a red object appear to be if you shone a green light on it?
it would appear black.
What colour would appear when a blue object is shone on by a red light?
A blue object appears blue because it absorbs most colors and reflects blue light. However, when a red light shines on a blue object, the blue object would absorb the red light and reflect blue, so it would still appear blue.
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.
