Preferred bulb colors for T5 setup's

[spawn]

I'm just wondering what bulb combo's people are currently running that they feel are giving them the best colors, especially purple's, using only T5 lighting. My color's are quite good for green's, yellowy green, orange, red, blue, but I think my purple's could be better, & with a new light coming I'm looking for suggestions to help the purple's pop. oh Yeah Sps domintent setup. My current setup with KZ from front to back with a 6 bulb is. Changing from stock RSM 250 Hood to a Tek Light for better reflectors.
