I believe we all have inner resources which we could make good use of as painters, but which we have not learned to trust.

Make up a color that unifies the first two. Its job is to make a bridge between the two that didn't go
We may not always agree about dissonance or harmony!
Do this several times, and bring them all in to critique. We will study how and why the bridges work.
