color detection using ldr

Hi guys i just wanna seek some help from you, I'm building a ldr base sensor im using a super bright led red,blue and green also the output of the ldr is being feed to a ADC0804 to be used with my PIC16F84A. Is there anybody that can give me a circuit for this sensor, that would help a lot.
