Color Format Converter
Edit any format — HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, or a CSS color name — and every other field updates instantly. No conversion button, no page reload.
Closest named CSS color — may not be an exact match.
How to use the converter
- Type into any field — HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, or a CSS color name.
- Every other field updates instantly as you type, no button press needed.
- Or use the native color picker for a quick visual pick.
- Copy any value with the copy icon next to it.
What the output means
HEX and RGB are the most common web formats. RGBA and HSLA add an alpha (opacity) channel. HSL describes hue, saturation, and lightness — often more intuitive to adjust by feel. HSV (hue, saturation, value/brightness) is common in design and image-editing tools. CMYK is the subtractive model used in print. The CSS Color Name field shows the closest CSS Level 3 named color.
Common use cases
Convert a designer's HEX swatch into the RGBA needed for a CSS overlay, translate a print CMYK spec into a usable HEX for the web, or check what a color looks like as a friendly CSS name.
Frequently asked questions
Which formats are supported?
HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, and CSS Level 3 color names (like rebeccapurple).
What happens if I type an invalid value?
That field shows an inline error and the other fields simply stop updating until you enter a valid value again — nothing silently clamps or resets.
What if my color doesn't have an exact CSS name?
The Name field shows the closest named CSS color, which may differ slightly from the exact color. Typing an exact name always sets the color precisely.
Does the converter store anything I type?
No. Conversion happens instantly in your browser and nothing you enter is saved or transmitted.
