The only combination of quark colors that produces a white baryon is RGB. Identify all the color combinations that can produce a white meson.
This is College Physics Answers with Shaun Dychko. We need to list all the possible color combinations of quarks in mesons that produce white. So for a meson, it can only have two quarks and to produce white, you need to have a color and its anti-color corresponding so you could have red and anti-red, green and anti-green and blue and anti-blue and these are the only pairs that will produce white and of course, you could have mixtures of these pairs in different mesons and there we go!
