So I'm trying to set up an RGB crystal chamber with the Petit Crouton 3.5, and honestly I don't really get the instructions for wiring in the manual. I'm not sure what resistors I need, what wires should go where, etc. I browsed for a bit and couldn't find a post about this.

The saber is set up with a R/G/RB tri-cree, and I'm going to be driving that with a CEx board. I want the chamber to match the blade color. Any help would be much appreciated.

Specs that might be important:
Petit Crouton v3.5
3.7 volt 18650
RICE port
Color Extender
Microtivity 5mm RGB common cathode LED (B:3.2 V/G:3.2V/R:2.0V)
Red/Green/Royal Blue tri-cree LED
