Image Hue Rotation
Image Hue Rotation lets you rotate image colors around the luminance axis while retaining alpha. Choose a photo to begin.
- Download a processed PNG
- Adjust hue angle (degrees)

Method and calculation
Rotate image colors around the luminance axis while retaining alpha.
Inputs and settings
Image Hue Rotation accepts Hue angle (degrees) (minimum -360, maximum 360).
Worked example
Image Hue Rotation example — Hue angle (degrees): 90. Preview instructions: Select a still photo, then use Hue angle (degrees): 90. The result is a PNG with rotate image colors around the luminance axis while retaining alpha.
Output and limitations
Hue rotation changes color relationships without rotating the physical photograph. A ninety-degree setting moves reds, greens and blues around a luminance-axis matrix. Clipping can affect vivid colors, so the result is a creative recoloring rather than a pigment simulation.
