I really thinking you should research more.
Bettas are not picky with any colored males or females. You Need a better understanding of betta behaviour. Depending on the other gender, the Betta will wiggle in a certain pattern than when they are ready to spawn.
When betta do a bending wiggle where it looks like the male is "slapping" it's a territorial sign and he is not ready to spawn. It is basically a warning.
When the male is waving it's body with a smoother snake like pattern, he is trying to attract her over to his nest or if he doesn't have one, he's displaying that he is ready to spawn.
I must say that there is absolutely no female or male in that case that is "picky" from a light color to a dark color. Bettas are not racist and it will not matter. You just have to look for signs indicating if they want to spawn or not.
Please do your research, it's very important. Honestly the question you asked is very simple and if you did even some basic research you would have known this. Betta behaviour is one of the most essential things that you need to know when breeding.
Also are you ready to breed? Do you have all the necessary requirements and materials to do so? Not only speaking about the things needed to get an actual spawn, but live foods and containers for the fry?
I've learned a bunch about breeding from www.bettysplendens.com
, and other sites. It's important that you do your research before breeding any animal for that case. I myself am a breeder and encourage people to breed only of they are willing to do their homework first.
I encourage you to also ask questions as many and as much as you want to. It's important that you know what your doing. So I don't want to discourage you from breeding or asking questions so please don't take this as I am trying to stop you from breeding. Yes we are here to help, but there have been too many breeders that are irresponsibly breeding and wondering why their fish are dying, which, injured, or being ripped apart.
