Maybe people with RGB's chips can chime in. But I do like 3 to 1 blues to white. Because the whites just get too bright. I do enjoy the color the purple pluses add when I have both on. So I imagine UV color is gonna be close.

I add some pop with 2 purple pluses and other t5 bulbs. It's all preference. Growth can also be attributed to other factors, (calcium, alk, trace elements, available food and light duration).

If you check peoples led tanks first, you will see first hand what you really want. People with DIY and Radions.
