Burgundy, navy blue, violet, teal, hunter green
navy is classic and pretty but light blue if u want something more out there
i love nvy, white, black and charcoal grey
Navy blue, Hunter green, burgundy, some lighter purples and blues
Mostly anything looks good on greys but I rarely put yellow on my grey just because is does bring out urine stains.
I like reds and blues on grey horses
Turquoise, blue, green, red wine, etc.
To me every colour but White. I personally like Red, Orange and Blue tones best
Everything but white and pastel yellow. Imo, they look best in jewel tones though.
