Current scaling factor for red channel LEDs on a scale of 0-255.
This setting adjusts the brightness of red pixels relative to other channels by scaling
the amount of current flowing through them. 255 equals led-max-current.

This setting adjusts the brightness of blue pixels relative to other channels by scaling
the amount of current flowing through them. 255 equals led-max-current.
gamma:
type: array

description: |
Gamma correction lookup values.
The gamma values make the LED brightness seem more linear to human eyes.
Default values match the recommendation from the IC datasheet but note that this may
