Black. A banana appears yellow in white light, which is a strong hint
that it reflects only yellow light and absorbs light of all other colors.
the tomato would appear black.

BLUE
A red rose would appear darker and less vibrant under blue light due to the interaction between the blue light and the red pigments in the rose petals. The blue light would not enhance the red color of the rose, making it appear different from how it looks under white light.
BLACK because the apple absorbs the blue light and there would be no light to reflect.
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.
The yellow cloth would appear dark under cyan light, as cyan light absorbs yellow. It would appear brownish-gray under blue light, as blue light is the opposite of yellow on the color wheel and would cancel it out.
Green
Black
Blue jeans would appear darker under green light due to the way light interacts with the dye molecules in the fabric. Green light may not complement the blue hue of the jeans, potentially distorting how they are perceived.
A red ball would appear black in blue light because red objects absorb blue light and reflect little to no light of that wavelength. This causes the red object to not reflect any light back to our eyes, leading us to perceive it as black in blue light.
The blue sky would appear green under green light because the green light would dominate the color seen by our eyes. The color of the sky is determined by the light that is reflected off of it, so when green light is shone on a blue sky, the green light will be the dominant color that is reflected.
