rgb-scaling:
type: array
required: true
description: |
Current scaling factor for R, G and B channels in the 0-255 range.
This setting will adjust the brightness of the respective color pixels relative to each other
by scaling the amount of current flowing through them. 255 equals lex-max-current.
gamma:
type: array
required: false
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
or may not apply for your particular LEDs.
