If your new bike is painted so that it looks red, what color of light is reflected by the paint?

The color you perceive from an object is due to the object absorbing all the other colors from the visible spectrum of light except the color the object is itself.  In your question's case, the bike absorbs all the other colors from the visible spectrum of light except for the red light.

It will be red, I took the test already k12 Usa testprep,
