A red ball would appear black under blue light.
if a red cricket ball was viewd in red light it would appear to be the colour of black or blue that's what colour you would be if it hit youin the face lol.
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.
If light has no red or blue, you would see the color green. Green is a combination of yellow and blue wavelengths, and when there is no red or blue light present, the resulting color perceived by the eye is green.
A blue book would appear more black or dark in a red light because the red light would overpower the blue color, making it difficult to distinguish other colors.
A cyan ball would appear dark or dim under green light because cyan is composed of blue and green light, so without the blue light component, the ball would only reflect the green light, resulting in a darker appearance.
