What colour will a green object be if only blue light was shone on it?
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.
What color will a red object appear under green light?
It would appear black because the object would not reflect any of the colors of light back.
What colour would a red object seem to look like if you only shined green light on it?
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
What colour will a white object appear if only red light was shone on it?
Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.
What color object would reflect more light?
White, since we can only see the color when all of the light hitting it is reflected.
Would a black microscopically flat or smooth object reflect light?
A flat object would reflect light but it depends on what sort of flat object is it.
What color would a green object under red light?
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect
What colour will a green object be if only blue light was shone on it?
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.
What objects reflect and absorb light?
Any object you can see reflects light. If it did not reflect any light it would be invisible. Similarly, no object is so reflective that it reflects all light. The proof that it absorbs light is that it increses in temperature as it is exposed to light.

What does a ''colorless'' object look like?
A colorless object appears white or transparent. It has no specific hue or shade and does not reflect or absorb any particular wavelengths of light to create a color. Instead, it reflects all visible light equally, resulting in a colorless appearance.
What color object would reflect more light?
White, since we can only see the color when all of the light hitting it is reflected.
What would a red object look like under a yellow light?
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.
How does white paper reflects heat?
We see color based on the way objects reflect light. Different wavelengths of light are different colors, and the light that an object reflects is what we see. For example, a red ball reflects red light, and so we see the ball as red. Any light that the object doesn't reflect is absorbed, so the red ball would absorb all the light that isn't red. This light then turns into heat. In science, white is the absence of light, and so white objects reflect all light. This means that the object isn't absorbing any light, and so the object isn't absorbing any heat.
What color would a green object be if you shined an orange light on it?
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.
