Halter Purple Horse

ok so my husband and i own this filly and we can not decide what to color to put her in, he says purple or pink, i said a different color because we all ready have purple and pink in the barn and i don't want to get stuff mixed up even tho all horses are mine in one area i would still like to have something different but anyways, this filly is chestnut with a flaxon main and tail, with white blaze and four white socks! she is an arabian, so it might be hard finding something! like right now she has a hot pink blanket(not on) and a purple halter on(we tried to find same size in same color but didn't work! so what do you think we have decided to let you guys and gals pick for us! thanks and pick a good one!
we already have a royal blue too

thanks so far!
