What about just putting red/green/blue colored filters in front of photoresistors?

thanks for the info....so the components needed just the LDR, red LED, blue LED, green LED and a filter?? just like that, rite?

Filters? Are you sure you aren't thinking of tinted lenses? (entirely different!)

Well, the LED's must have resistors placed in serial, but yea thats all you need.

Tinted lenses, AKA color filters.
