The answer lies in the name you've given to the rose.

You call it a "red rose", because when it's illuminated by light of all colors, it absorbs

all of them except the red, and the red remains to bounce away from the rose toward

your eye.

If the only light falling on it is green, then all the light falling on it is absorbed. There's

none left to reflect away from the rose to your eye, and the rose appears black.

In green light, the red rose appears black because the pigments in the rose absorb green light and reflect little to no light back to our eyes. Since there is no red light present to be reflected, the rose does not appear red and instead looks black to us.

Why do red rose petals look black when you shine green light on them?

This phenomenon occurs because red rose petals absorb green light and reflect back very little of it. This lack of reflection causes the petals to appear black when illuminated with green light.


When green light shines on a red rose why do the petal appear black?

The red rose appears black when green light shines on it because the green light is mainly absorbed by the red pigments in the petals. Since the green light is not being reflected or transmitted, the petals appear black to our eyes.


When a red rose is seen through green light it appears?

When a red rose is seen through green light, it may appear darker or less vibrant than when seen in white light. This is because objects absorb certain wavelengths of light and reflect others, so the green light could be absorbed by the green parts of the rose, creating a darkening effect.


Which color will red rose appear to be if only a blue light reached it?

Why do you call that flower a "red" rose ? Could it be because it appears red in typical 'wideband' solar or household light ? That must mean that when light of many colors shines on it, the rose absorbs everything except red, and red is the only light left to bounce off of it toward your eyes. If that's the case, and you illuminate it with light of any single color other than red, then the rose will absorb that light and appear black.


What colour would a red rose appear under blue light?

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.
