computeAdjustment()

CRGB CRGB::computeAdjustment ( uint8_t scale, const CRGB & colorCorrection, const CRGB & colorTemperature )

static

Calculates the combined color adjustment to the LEDs at a given scale, color correction, and color temperature.

Parameters

scale	the scale value for the RGB data (i.e. brightness)
colorCorrection	color correction to apply
colorTemperature	color temperature to apply

Returns

a CRGB object representing the adjustment, including color correction and color temperature
