在HEX、RGB、HSL、HSV和CMYK之间转换颜色。
Frequently Asked Questions
What CSS color formats does this tool support?
Supported formats: HEX (#RGB, #RRGGBB, #RRGGBBAA), RGB/RGBA, HSL/HSLA, HSB/HSV, CMYK, and all 140 named CSS colors (red, dodgerblue, coral, etc.).
What is the difference between RGB and RGBA?
RGBA adds an alpha (opacity) channel to RGB. Alpha ranges from 0 (fully transparent) to 1 (fully opaque). rgba(255, 87, 51, 0.5) is the same color as rgb(255, 87, 51) but at 50% transparency.
How do I convert a named CSS color like "coral" to HEX?
Enter "coral" in the input field and the tool looks it up in the 140 named CSS colors: coral = #FF7F50 = rgb(255, 127, 80). All CSS named colors are supported.
What is HSB/HSV and how does it differ from HSL?
HSB (Hue, Saturation, Brightness/Value) is used in Photoshop and many design tools. HSL (Hue, Saturation, Lightness) is the CSS standard. Both use a 0-360° hue wheel but define the other two channels differently.
Can I convert colors with CSS custom properties (variables)?
Enter the actual color value, not the variable name. Resolve --my-color to its value first, then convert. The tool works with actual color values, not CSS variable references.
