What color? Bridle combo

I found two bridle combos for only $10 in my area =D So excited as I tried one out and looooved it!...now I have to give it back as the daughter said she wanted to keep it after all But I found one in sun yellow and in red..not sure what color to pick. I love both! She has a red and black breastcollar that would work well ad my saddle pad is black..what color do you think?

Go with the red, so I can buy the yellow :)
Haha, just kidding. Either would work well with a black/white horse, and the yellow is pretty darn awesome. But, other yellow tack is hard to find, and red is everywhere.

I think,think,think I might actually go with red as it's my fav. Color and the dirt won't be as noticeable =D I know it seems to be everywhere but I actually see more pink ,greens,and blues..plus there will be a breast collar that is red and I need one.

SOOOOO if my friend doesn't want the yellow one I will sell it :) goign to see if it will fit one of her horses.
