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.
Green
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.
It is either green because the colour of light above it is the only colour it allows through like in this case Green light only lets green through or it could be cyan as blue and green make cyan but i think it would be green
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.
You would get a greenish color when mixing light blue and yellow.
Not much different. It probably would just have this green-ish tint to it.
A green object will appear dark or black under blue light because it does not reflect blue light well. Green objects absorb blue light, resulting in little to no reflection of this color.
A green object will appear black if only blue light is shone on it because blue light is absorbed by the object and green is the complementary color of blue.
Black and blue, respectively
An object that appears blue in white light does so because it absorbs all colors except blue, reflecting blue light. However, in green light, which does not contain any blue light, the object cannot reflect blue light and would therefore appear grey or black as it does not have any other color to reflect in the green light.
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.
