→Tonemapping
A tone mapping shader allows you to use an external LUT texture to do tone mapping and other color adjustments.<ref name="tonemapping">http://filthypants.blogspot.com/2017/06/retroarch-tone-mapping-lut-shader.html</ref> The LUT texture is PNG image that can be edited in any image editing software to have the desired color adjustment. When the modified LUT is used in the shader, the color adjustment gets applied to the game's video output.
