This reduces the blend to affect only the saturation of the base pixels. Color This applies the blend by creating the resulting pixel using the luminance of the base pixel but the hue and saturation of the paint brush pixel. This limits the blend so it doesn t affect the brightness of the base pixels. Luminosity This applies the blend by creating the resulting pixel using the hue and saturation of the base pixel but the luminance of the paint brush pixel. This allows you to apply it so it affects only the brightness of the base pixels.
