Do electrons have a color? No, electrons don't have an intrinsic color since they are reflectors of em waves. They are more like perfect mirrors. If there is a fundamental em wave associated with an electron it would be at a wavelength far too short to be visible (ie. a color). Perfectly good question that deserves an answer.
Ok, I've answered your question. Now would you answer mine? What is the size and shape of a photon? If that's too hard, maybe you could start by saying whether a photon moves or not and at what speed it moves. I was under the impression that a photon from the Sun takes around 8 minutes to reach the Earth. Is that not true?
As an aside, if a unit step em wave hits a stationary point electron, at what distance from the point electron is the reflected wave's electric field equal to and opposite that in the input unit step? What is the significance of the distance? Of course, I'm asking for a classical analysis, if can lower yourself that far.
