If you are truly concerned about racing ability, you might ‘go backwards’ and rank horses by ability to sire runners, then affordability, then color.
Realistically, unless your mare is a producer of great runners, you will do better to go for great conformation and the secondary market of eventers /hunters /jumpers in your stallion selection.
So no ‘odd’ legs, coarse heads, loooong backs, downhill as an adult or ugly -spastic temperament.

Thanks D_BaldStockings! That’s kind of what I’m doing.
I don’t mean to sound wishy-washy. I mean, I’m wishy-washy on this idea. I’ve always been fascinated by color genetics and would like to try. But, I’ve spent basically my entire adult life involved with race breeding, so it’s going to keep coming to the forefront.
This horse is for myself. My primary interest lies in racing, beyond that I’ve done a little bit of everything. My goal from the color breeding endeavor would be to hopefully produce something with color (not just 4 whites) that will hopefully race. I’d also like the horse to be useful for something after it is done racing, or if it can’t race, or if the unthinkable happens and I can’t keep the horse. But since the horse is for me, I’m not just going to totally throw the racing bag out the window, since that is my primary interest.
I know I can find plenty of chromey racing stallions. I know what I’ve got as a racing broodmare and what she crosses with from a racing standpoint. I’ve evaluated her with just about every racing stallion within driving distance in my price range.
What I’m looking to learn more about are the “guaranteed” color producing options out there that actually are known to carry the frame gene (or DW gene). I understand I’ll have to compromise on racing ability with those guys, which is why I’m looking for more in depth info on them. If I go that route, it’s going to have to be the “right” horse. 
And really, now I’m just enjoying looking at pretty stallions, so keep 'em coming!
