I like your jumble of colors, they look just right to my eye. I notice that you have a very generous amount of neutrals in tan, grey, brown, cream. I have two questions for you: What fabric will you use for the backing? I think a neutral would be very nice. And the narrow white strips that separate the colors, Will you also put a white strip around all your blocks, so that the outline continues to the edge of the Triangles? I hope the answer is yes. Then, I would choose 5 colored fabrics for your side triangles, and mix them up all around your quilt. I imagine this with a tan/brown backing and 5 various neutral colors making up the Triangles--that's what I would do. OR--if this is a gift ?? Ask the recipient what color they would choose, let them be your co-creator. That's half the fun.
