So I'm making a small led build for a 5 gallon cube I'm working on, and I've decided to run 5 LED's in a layout similar to half of one ai nano

The blues will be 2 Royal blue and 2 blue 3w and the white is one 5w cool white.

I then though that I should make this as full spectrum as possible with 5 LED's so what do you guys reccomend? I could do a UV and maybe a red LED? Let me know what's the best color combo you can think of using 5 LED's
