All other colours except red are absorbed.. The reason it seems red to our eyes is because only red colour is reflected back.
Objects have color because of the way they interact with light. When light strikes an object, some of the light is absorbed and some is reflected. The reflected light is what we see as color. The specific color we perceive is determined by the wavelengths of light that are reflected.
A green object under green light would appear its original color and shade of green. When an object is illuminated by light of the same color, no new colors are absorbed or reflected, resulting in the object appearing unchanged.
If the wall reflects light in the 400 to 500 nm range and absorbs light in the 600 to 700 nm range, it would appear to our eyes as a color that falls within the reflected range (blue-green) and not in the absorbed range. The absorbed light would not contribute to the perceived color of the wall.
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.
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
That would be black.
black
Obviously the excact same Red.

To do this, it would have to be black, which is the lack of color.

The color of the jello would be the complimentary color of the absorbed light. For example, if you have red jello, that means it is absorbing green light, since green is red's complimentary color.

The color you perceive is determined by the wavelength (or frequency) of the light.If it was determined by the intensity of the light, then a street light would steadily change coloras you approach it, pass it, and recede from it. That might be quite beautiful, actually.But where I live, it doesn't happen.
Colors arent the 3 primary colors, its the 7 colors of the rainbow ROYGBIV(Red,Orange,Yellow,Green,Blue,Indigo,Violet) What happens is... well the life of all color is light, without light there is no color, cause light has all these colors (ROYGBIV) When something is red, that means that everycolor from light is being absorbed EXCEPT Red, red is being refracted or kicked out, when something is black, non are being absorbed they are all being refracted, when something is white, all the colors are being absorbed. When there is no light, there is no color, and we wont see color cause it would be to dark to see.
