I was wondering if anyone could help using Arduino to run RGB LED's and do color mixing. I was wanting to make a DMX receiver.

Hi,

if you search for DMX there are some solutions for the arduino (look at Arduino Playground - DMX.
For a color led you can use 3 DMX addresses, each of them giving the value for one of the colors red, blue and green.

If it is just one LED then connect each colour element to a PWM pin through a suitable resistor. If you want more then a driver like the TLC9540 is the way to go.
