I use 660 red and neutral white. I chose neutrals because they still have a large peak in the blue range and they're more of a full spectrum bulb.

Lately I've seen a lot of guys opting to use u.v. Or violet either with or instead of blues. Aiming more for the actinic range around 420nm or so.

But you can actually grow copious amounts of algae using just the 660nm reds alone. I can confirm they grow quite well all by themselves.
