When you say "blues" are you talking about tomocerus? Those are usually referred to as "blacks/silvers," the only blue springs I've seen are Podura which are TINY and are noticeably blue.Temperate and tropical both do fine in all of my tanks.
I'm working with 3 types now. Whites which are pretty small and boom in my cultures. Pinks which are a bit larger and really take off. And blues, which are larger still (actually I've found they are quite variable in color) but aren't as prolific as the others. At least not yet. Not sure I've found the key to raising these yet. Although it appears they almost totally ignore active yeast as s food source.
By the way. I will have several pink and white spring cultures for sale next week. Hopefully the blues will be available soon as well.
Good luck... It seems I've also caught the bug, "bug" lol
