Schematic Check for Color Organ
Problems:


1V won't light any led.
You have NPN transistors on the led high side.


Everything else seems okay I guess.

The envelope detectors seem unneeded, most color organs I've seen don't use one. Probably not an issue but response will be affected, as it will be less sensitive. It depends on how flashy you want it really. 

And the specific values of the parts are completely important to how the band pass filters and envelope detector works, so you need to figure those out.
