Good color to Show in

Sorry but I don't have a picture of my mare. She is a chestnut roan Appaloosa mare, with frosting, snowflakes, and roaning over her topline, stockings on both left legs, 1/2 a stocking on her right rear leg, and a pastern on her right for leg. Along with a dorsal stripe and all of the Appalooa characteristics. I hope this description has helped you.
I am buying new western contesting and show tack and I needed a color that would look good on her. Thank you for the trouble of helping me.

I've always like a turquoise or purple on chestnuts. Blues and hunter green are always a good color to go with too.

Blues, turquoise and light greens. I've seen some bright reds look good
