ah sorry!Please don't post unsolicited anti-breeding opinions in The Rabbitry
Saying "Well in reality you shouldn't breed bunnys, their are wayyyyyy to many abandoned ones at shelters that need homes So please consider getting your rabbits spayed!" Is unsolicited anti-breeding advice and this is not the place for it. You don't know what purpose they might have for breeding these rabbits. Constructive advice might be something like "make sure you are breeding these rabbits with a purpose, not just to get cute kits or to try and sell pets - it's hard to sell kits when the market is oversaturated with pet quality rabbits". A blanket statement like this doesn't help.
As for your question - it depends on a lot of factors. What breed is it? What are you trying to achieve? A self color like a black is probably a pretty safe bet. Sooty fawn usually pairs pretty well with both blue and with seal point. If you are breeding for show, look for type first, before you start looking at special colors.
