I think this is an arbitrary "computerification" of the problem, and doesn't really make things clearer.

  Yes it doesn't quite feel right, but the problem as posed also doesn't quite seem rigorous enough, leading to some of the confusion in the answers here with people saying it seems easy. Maybe two VMs, identical program loaded on both, pick a leader through synced messages. You can't do this unless there is something different about the VMs. If one VM goes first it's easy (just use its suggested color), if there is a hardware RNG, easy (iterate until one VM rolls higher than the other, then use the last suggested color from that VM). If the programs are different (as "maximally logical" is vague), then it comes down to some kind of analysis of the output of an arbitrary program, which is impossible in the general case. You then have to assume some kind of shared knowledge (red most likely, rgb averaging is most likely way to blend, known mots likely ordering of colors such as alphabetical) to make progress.
