Everything you need to know about Hue
Hue rotates all colors in your image around the color wheel by a specified angle. This shifts every color uniformly – reds become oranges, greens become blues, etc. – while preserving the original brightness and saturation relationships.
Parameters
- Hue
The rotation angle in degrees (-180° to +180°). At 0°, no change occurs. Positive values rotate colors clockwise on the color wheel (red → yellow → green → cyan → blue → magenta). Negative values rotate counter-clockwise. ±180° produces the same result – completely opposite colors.
How It Works
The filter converts the image to YIQ color space (used in analog TV broadcasting), rotates the I and Q chrominance components by the specified angle while keeping Y (luminance) constant, then converts back to RGB. This preserves perceived brightness while shifting all colors uniformly.
Common Rotations
- ±30° – Subtle color shift, neighboring colors
- ±60° – Moderate shift, noticeable color change
- ±90° – Dramatic shift, significantly different palette
- ±180° – Complementary colors (opposites on the wheel)
Tips
- Use small values (±10–20°) for subtle color correction or warming/cooling
- Large rotations create surreal, psychedelic color effects
- Try ±180° for a striking complementary color inversion
- For more control over individual colors, use selective color tools instead
