The Hue blend mode applies the hue of the blend color to the base image while retaining the luminance and saturation of the base image. It gives the base image a tinted effect where the tinting is darkest in areas of high saturation. Where the blend color is a shade of gray (0% saturation), the base image is desaturated and where the base image is gray, the Hue blending mode has no effect.
The Hue blend mode can be used for color replacement, such as in my tutorial for removing red eye.
