I just did some more testing. i hooked up a 50 to the red, and ran 3.3 to all 3 anodes. It looked a little blue, so I hooked up a 50 to the blue, and a 63 to the red. I then measured the diodes
I found the green, with no resister measured 3.24, red measured 2.15, and blue was 2.7
Red (3.3-2.15)/63=0.018253968
Blue (3,3-2,7)/50=0.012
Green (3.3-3.24)/0= ?
But it still looks like mostly blue
I measured the voltage across the resisters, and the blue measures .49, and the red measures 1.
Im assuming with all 3 LEDs on, it should be white, and any color variance should be adjusted with a resistor.
