For now, you can change the color of the LED effects by hardcoding it in the firmware.
Bazecor only supports changing the colors when in the colormap.
The light effects can be changed by code and not via Bazecor.
Both the ripple effect and breathing can be changed by modifying the firmware (adding LEDBreathEffect.hue = 0 or WavePoolEffect.ripple_hue = 0 (where 0 is the hue of the effect, see https://en.wikipedia.org/wiki/Hue for a rough overview of what number corresponds to which color)) and recompiling.
