Hi Everyone. I am confused about the science of colors. I will use an example in my question. I know that the color blue is caused by atoms reflecting blue wavelengths of light and absorbing other wavelengths of light. What I don't understand, however, is which part of the atom actually absorbs the other wavelengths of light? Does the atom as a whole absorb the wavelengths other than blue, or do its electrons do that? If the atom as a whole absorbs these wavelengths of light, how does it do that? And if electrons are responsible for absorbing these wavelengths of light other than blue, why don't they emit these colors when they drop back down to a lower energy level?
