SDL_SetRenderColorScale

sdl render

Set the color scale used for render operations.

The color scale is an additional scale multiplied into the pixel color value while rendering. This can be used to adjust the brightness of colors during HDR rendering, or changing HDR video brightness when playing on an SDR display.

The color scale does not affect the alpha channel, only the color brightness.
