## Main Question or Discussion Point

Hi this is a very elementary question. Is the strong force a color force? Or a favor force? Or a combination color and favor?

Also with photons (massless) we have a r^-2 force but with massless gluons the force increase with r (do not know as what function) how can this be?

Thanks.
