Because green is the color being reflected, and the other colors are absorbed
it will look black but I am not sure
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
You have some problem with your eye.
When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.
A red object will appear dark or black in a green light because red objects absorb green light instead of reflecting it. This phenomenon occurs because the color of an object is determined by the wavelengths of light it reflects.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
A pure green object would reflect the green third of the spectrum, and absorb the red and blue portions. Magenta light is composed of red and blue waves so they would be absorbed by the green object. Therefore, in theory, a green object would appear neutral, virtually black. But this assumes that all the colors are very pure and perfectly balanced. This is unlikely, so the object would most likely look near neutral with some color skewing one way or another.
You see the colors of light that are reflected off the object. The colors you see depend on the wavelengths of light that the object reflects. For example, if an object reflects green light and absorbs all other colors, you will perceive the object as green.
A red object would appear dark or black in green light because red objects reflect red light and absorb green light. Consequently, there would be little to no red light reflecting off the object in green light, resulting in a lack of color perception.
A green object illuminated by blue lights would likely appear to have a bluish hue. The blue light would mix with the green, potentially creating a teal or cyan effect, depending on the intensity of the blue light and the specific shade of green. This color blending occurs because the blue light affects how our eyes perceive the green object. Overall, the object may look less vibrant and more muted than it would under white light.
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)
