I'm breeding Taiwan Bees now for about 2 years succesfully. Have loads of Panda, King Kong, Wine Red, Red Ruby, Blue Bolt and some Green Hulk.
Now as the numbers are good, I want to set up some projects. Pinto, but especially want to get Deep Blue Bolt.

How do I get my Blue Bolt a more deep blue color? Which Taiwan Bees should I crossbreed?
Thanks in advance!!
