it would be a lighter shade of red...!
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect
It would appear black because the object would not reflect any of the colors of light back.
Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
If there were no Sun, and no other source of radiant energy, the plants (and the entire planet) would quickly freeze. And since the color of an object is determined by the color of the light that is reflected by the object, with no light there would be no color, and everything would be black. If we grow plants under artificial light on a space station, then the light on the space station (even if artificial) would be the same kinds of light that we humans prefer, so the plants on the space station would continue to be green.
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.
White, since we can only see the color when all of the light hitting it is reflected.
A "green" object is called "green" because that's the only color of light it reflects, and it absorbs any other color. If orange light is shining on it, then there's no light for it to reflect, and it looks black to you.
The cloth would be wite because if it were any other color the colored light would mix with the color of the cloth and make a different color.
it would appear black.
Any object that has light shone on it would appear in a particular color because the said object absorbs all the other colors of the spectrum and reflects one single color. when the light itself consists of a single color, the color of the object gets modified because the reflected light contains the color of the light and then part that is reflected. For ex, the wall in the question would appear red if the light is only one wavelength but would appear as a combination of red and its own natural color if the light is a combination of different wavelengths.
Pink.
An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
