I have just brought a new horse she is a mare and her name is kelly, im getting alot of new stuff for her but i cant realy do that untill i find the colour that goes best with her, ill atach a picture of her.
Green goes well on a bay horse, but I think a lot of people use green already. I like purple and pink on bay a lot. Bay can carry any colour really well though, they are the brunettes of the horse world
Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.
I've always been a sucker for a hunter green on my bright bay (now if only I could get the money to get some matching tack ), I always love to compliment their natural color, so I use a lot of dark black as a compliment color- it makes Indie's black points stick out more.
You can also look at some reds, sometimes they don't clash too badly and can really make you look flashier.
Edit: By the way, Kelly is gorgeous! Love her color and her build.
