In addition, the signal pins on the DSC will likely not be able to provide enough current for lighting bright LEDs; in this case you have to use a signal amplifier, such as a homebrew solution using transistors and other discrete components or a COTS solution such as s solid-state relay. Mechanical relays (such as a Spike) will likely not be able to switch fast enough.

Edit:
To actually pink which color you want to generate, look up HTML hexadecimal color charts. Hexadecimal is a base-16 number system, where 0-9 are the same, but A=10, B=11, and so on until F=15. So for example, FF in hexadecimal would be 255. The sequence is 2 digit red, 2 digit green, 2 digit blue, so the hexadecimal color #FF6600 is 255 (out of 255) red, 102 (out of 255) green, and 0 blue.

To convert these three numbers to a generic duty cycle, divide by the large possible number (255). So it becomes

Red: 100%
Green: 40%
Blue: 0%

Which will generate the color orange.

For the pwm which color goes where in the PWM(the red, green, and blue wire)? and where does the common wire go(the black wire)?
