1. A device, comprising:
a processor to:
decrease a value component of a pixel input in hue-saturation-value (HSV) color space to generate a decreased value component;
modify a saturation component of the pixel input based on a hue-adaptive non-linear saturation mapping function to generate a modified saturation component to offset the decrease in the value component;
generate modified HSV components of the pixel input comprising the decreased value component and the modified saturation component; and
provide an output to an organic light emitting diode (OLED) display panel based on the modified HSV components of the pixel input.
