Red rose petals reflect red light.
It absorbs all other colors, including green and blue.
Therfore it absorbs the green light and the petals appear black.
When you mix red and blue, you get magenta. When you shine a green light on magenta, the green light will be absorbed by the magenta, resulting in a dark color or black, depending on the intensity of the green light.
When you shine a green light on a green object, the object will reflect the green light and appear brighter or more vivid in color. Green objects absorb most of the other colors of light and reflect green light, so they will be most visibly affected by green light.
When green and red light shine on a green leaf, the green light is mostly absorbed by chlorophyll for photosynthesis. The red light is less efficiently absorbed, so some is reflected back, leading to the leaf appearing green to our eyes.
If you shine red light on black paper, the black paper will absorb most of the red light and appear dark. The red light that is not absorbed may be reflected or scattered, but it will not significantly change the appearance of the black paper.
Things appear red because they absorb all wavelengths of visible light apart from red this will be reflected. If you only shine green light on the object it will all be absorbed and no light will be reflected so it will appear black.
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
blue
When you mix red and blue, you get magenta. When you shine a green light on magenta, the green light will be absorbed by the magenta, resulting in a dark color or black, depending on the intensity of the green light.
If you shine a green light on a red cap, the cap will likely appear dark or black because red objects absorb green light and do not reflect it back to our eyes. This is due to the color mixing phenomenon where red and green cancel each other out.
The cap is called 'green' because it absorbs all other colors of light, leaving only the green light to bounce from it to your eyes. If no green light shines on it, then there's no light to bounce from it to your eyes, and it appears black. If you only shine blue light on it, then there's no green light shining on it.
When you shine a green light on a green object, the object will reflect the green light and appear brighter or more vivid in color. Green objects absorb most of the other colors of light and reflect green light, so they will be most visibly affected by green light.
When you shine yellow light onto a green surface, the surface will absorb the yellow light and reflect green light. This is because the surface appears green due to its ability to reflect green light while absorbing other colors.

When green and red light shine on a green leaf, the green light is mostly absorbed by chlorophyll for photosynthesis. The red light is less efficiently absorbed, so some is reflected back, leading to the leaf appearing green to our eyes.
