What is an .AHU file?

.AHU is Adobe Photoshop HSL File

Hue Saturation Lightness (HSL) file used by Adobe Photoshop, a raster graphics editing application; contains preset values for the hue (0 to 360), saturation (0 to 100), and lightness (-100 to 100) components of color appearance; used for applying color adjustments to images.

NOTE: The "L" in HSL can also stand for "Luminance."
