Image Hue Rotate Rotate the hue of all colors in an image for creative color-shifting effects.

What Is Image Hue Rotate?

A hue rotation tool shifts all colors in an image around the color wheel by a specified angle. At 0 or 360 degrees, colors remain unchanged. At 180, every color shifts to its complementary opposite: reds become cyans, greens become magentas, blues become yellows. The tool uses the CSS hue-rotate filter on the canvas for GPU-accelerated processing. A visual color wheel gradient helps you understand how colors map at different angles. A creative tool for experimental photography and design.

Why Use Image Hue Rotate?

• Full 0-360 degree hue rotation with visual color wheel guide
• Preset buttons for common rotation angles
• GPU-accelerated CSS filter for instant processing
• Creative color-shifting for unique artistic effects

Common Use Cases

Creative Photography

Create surreal, otherworldly color effects by shifting all colors.

Color Variations

Generate multiple color variations of a design by rotating hues.

Pop Art Effects

Create pop-art-style grids using the same image with different hue rotations.

Accessibility Testing

Simulate color perception differences by rotating hues.

Technical Guide

Hue rotation uses the CSS filter hue-rotate() applied via the Canvas 2D context filter property. Setting ctx.filter = "hue-rotate(Ndeg)" before drawImage applies the transformation during rendering. The filter operates in the sRGB color space by converting pixel values to a hue-saturation-lightness representation, rotating the hue component, and converting back. This is GPU-accelerated in modern browsers. Achromatic pixels (grays, black, white) are unaffected since they have no hue component.

Tips & Best Practices

• 1
  Try 180 degrees for complementary color inversion — a striking effect
• 2
  Grays, blacks, and whites will not change since they have no hue
• 3
  Create a color palette by saving the same image at 60-degree intervals
• 4
  Combine with saturation adjustment for more controlled color shifts

Frequently Asked Questions

Q What is hue rotation?

It shifts every color around the color wheel by the specified degrees. 180 degrees gives complementary colors.

Q Why don't gray/black/white pixels change?

These are achromatic — they have no hue component.

Q Is 360 degrees the same as 0?

Yes, a full 360-degree rotation returns all colors to original values.

Q Can I rotate hue on just part of an image?

This tool rotates all pixels. Crop the target area first for selective rotation.

Q Does hue rotation affect image quality?

No, the canvas filter produces accurate color transforms without quality degradation.
