The hue-rotate() CSS function applies a hue rotation to an element and all its contents. It's part of the CSS filter property. Internally, it uses a color matrix transformation that shifts the hue of every pixel by the specified angle. A value of 0deg leaves the image unchanged, while 360deg brings it back to the original. Values can be any number — negative angles rotate counter-clockwise on the color wheel.

There is no strict limit — you can use any numeric value with the deg unit. However, since hue is cyclical (360° = full circle), values repeat every 360 degrees. So hue-rotate(400deg) is equivalent to hue-rotate(40deg), and hue-rotate(-90deg) is the same as hue-rotate(270deg). Common ranges are -360deg to 360deg.

Absolutely! You can chain multiple filter functions together. For example: filter: hue-rotate(90deg) brightness(1.2) contrast(1.1) saturate(1.5);. This allows for powerful image manipulation entirely in CSS. Note that the order matters — filters are applied sequentially from left to right.

Common uses include: Theme color variants (derive multiple color schemes from one base image), hover effects (subtly shift colors on mouse-over), image filters for photo editing UIs, animated color cycling using CSS animations, and accessibility adjustments for color vision deficiencies.

CSS hue-rotate() uses an SVG filter-based color matrix algorithm rather than a simple HSL hue shift. For pure saturated colors, the results are very similar. However, for desaturated colors (near grays), hue-rotate has less visible effect. The algorithm preserves luminance better than a naive HSL rotation. Our tool approximates the resulting color using HSL math for the swatch display, but the live preview uses actual CSS filters for perfect accuracy.

CSS filter: hue-rotate() is supported in all modern browsers, including Chrome, Firefox, Safari, and Edge. It has been available since ~2011–2013 across major browsers. For Internet Explorer, partial support exists via deprecated SVG filters. You can safely use it in production without vendor prefixes for 99%+ of users today.

Yes! hue-rotate is fully animatable. Use CSS transitions for smooth hover effects: transition: filter 0.4s ease;. Or use @keyframes for continuous color cycling: @keyframes rainbow { from { filter: hue-rotate(0deg); } to { filter: hue-rotate(360deg); } }. This creates a beautiful rainbow cycling effect, popular for loading animations and vibrant UI elements.

No — hue-rotate applies uniformly to everything within the element, including text, backgrounds, borders, images, and child elements. It treats the entire rendered output as a single image and shifts all hues. This means a white or black element will show minimal change (since they have no hue), while fully saturated colored elements will shift dramatically.

For a rough estimate, convert your color to HSL, add the rotation angle to the H (hue) component, and wrap around 360. For example, a blue at H=240° with hue-rotate(90deg) becomes H=330° (magenta/pink). Our tool computes this approximation and displays it alongside the actual CSS-filtered preview. For precise results, the CSS filter uses a more complex matrix but the HSL method is usually close enough for design work.

hue-rotate() shifts all hues around the color wheel while preserving saturation and lightness. In contrast, sepia() converts colors to warm brown tones, saturate() increases or decreases color intensity, and grayscale() removes all color. They serve different purposes: hue-rotate is great for color variation, while sepia creates a vintage/antique look, and grayscale is for black-and-white effects.
