I am a mathematician and not a physicist, so please be gentle to me.

The best explanation so far that I found about light waves was here: https://youtu.be/7eutept5h0Q

If I got it right, then light is a particle without mass which has magnetic and electronic energy and this energy is oscillating all the time. When one spot this particle, one sees a color which depends on the frequency of the oscillating energy. Is that correct?

Also every color in the below diagram may be observed by a single particle.

All other color that don't appear in the diagram (like white color) have to be a collection of light particles of differed frequencies which will appear to us as a single color?
