Hue Rotation Playground

Color Wheel Relationships

Understanding how colors shift during rotation:

• 90° rotation shifts primary colors to their neighbors
• 180° rotation creates complementary colors
• 270° rotation produces triadic relationships
• 360° rotation returns to original colors

Effect on Different Colors

How hue rotation affects various color types:

• Primary colors shift predictably around the wheel
• Grayscale values remain unchanged
• Saturation levels are preserved
• Brightness relationships stay constant

Performance Considerations

Optimize hue rotation implementations:

• Use hardware acceleration when possible
• Consider animation performance impact
• Test on various devices and browsers
• Monitor GPU usage for complex effects

How does hue rotation affect grayscale colors?

Grayscale colors (including black, white, and pure grays) are not affected by hue rotation since they have no hue component. However, colors with even slight saturation will shift around the color wheel.

Can I animate hue rotation smoothly?

Yes, hue rotation can be animated using CSS transitions or animations:

/* Smooth transition on hover */
.color-shift {
  filter: hue-rotate(0deg);
  transition: filter 0.3s ease;
}

.color-shift:hover {
  filter: hue-rotate(180deg);
}

/* Continuous animation */
.rainbow-effect {
  animation: rainbow 5s linear infinite;
}

@keyframes rainbow {
  from { filter: hue-rotate(0deg); }
  to { filter: hue-rotate(360deg); }
}

How do I combine hue rotation with other filters?

Multiple filters can be combined, but order matters:

/* Example filter combinations */
.filter-combo {
  /* Adjust colors first, then modify intensity */
  filter: 
    hue-rotate(45deg)
    saturate(150%)
    brightness(110%)
    contrast(120%);
}

What's the browser support for hue rotation?

Implement with appropriate fallbacks:

/* Progressive enhancement */
.color-effect {
  /* Fallback for older browsers */
  background-color: #ff0000;
  
  /* Modern browsers */
  @supports (filter: hue-rotate(0deg)) {
    background-color: #ff0000;
    filter: hue-rotate(90deg);
  }
}
