If a light contains red, green, and blue LEDs, you can create nearly any color.
Be careful of RGB lights that do not also contain white and/or tungsten LEDs, because without those, you may experience significant color reproduction issues.
The data in this table is listed in one of four ways:
None: Does not support RGB at all
Yes (RGB): Contains red, green, and blue LEDs only
Yes (RGB+W): Contains red, green, blue, and one set of white LEDs
Yes (RGB+WT): Contains red, green, blue, white, and tungsten LEDs (this is the best for both color accuracy and flexibility)
