See all conversions instantly
All equivalent formats update in real time: HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, and CSS custom property. Copy any value with a single click. -
Use the color picker
Click the color swatch or use the native browser color picker to visually choose a color and get all its format equivalents at once. -
Copy and use in your project
Click any format's copy button to send it to your clipboard. Paste directly into CSS, Sass, Tailwind config, Figma, or print workflows.
Example Conversions
The same blue color expressed in every supported format:
| Format | Value | Usage |
|---|---|---|
| HEX | #3b82f6 | CSS, HTML, Figma |
| RGB | rgb(59, 130, 246) | CSS, Canvas API |
| RGBA | rgba(59, 130, 246, 1) | CSS with opacity |
| HSL | hsl(217, 91%, 60%) | CSS, design tokens |

Common Use Cases
Web & UI Design
Convert brand HEX colors to HSL for CSS custom properties and Tailwind config, ensuring consistent theming across light and dark modes. convert JSON, CSV, and XML data formats
Print & Pre-press
Convert screen RGB or HEX colors to CMYK for print production — avoiding the common pitfall of colors that look great on screen but print dull.
Brand Guidelines
Document a complete brand palette in all formats — HEX for digital, CMYK for print, Pantone reference — from a single source of truth.
Accessibility Checks
Retrieve exact color values to test in a contrast checker, ensuring text and background combinations meet WCAG AA or AAA requirements.
Developer Workflows
Quickly translate design-tool colors (Figma HEX) into CSS HSL variables for dynamic theming and programmatic color manipulation.
How It Works
All conversions run instantly in your browser with zero server involvement.
The tool parses your input into normalised RGB values (0–255 per channel), then applies standard conversion formulas to each target format.
HSL (Hue, Saturation, Lightness) is derived from RGB by finding the min/max channel, computing lightness as their average, then calculating saturation and hue angle.
CMYK is computed from RGB via the formula: K = 1 - max(R,G,B); C = (1-R-K)/(1-K); etc. Note that RGB→CMYK is device-dependent — screen CMYK is an approximation, not a press profile.
Who This Tool Is For
Frontend Developers
Translate design tokens between CSS formats and quickly verify color values during development.
UI/UX Designers
Convert Figma or Sketch swatches to any format needed by your design system or CSS framework.
Print Designers
Convert RGB brand colors to CMYK before sending artwork to press, preventing color shift surprises.
Brand Managers
Maintain a single brand palette in all formats — digital and print — without switching tools.
Accessibility Testers
Extract precise color values for use in contrast checkers and accessibility audits.
Tips for Working with Colors
- Use HSL in CSS custom properties (--color-primary: hsl(217, 91%, 60%)) so you can adjust lightness with calc() for hover and disabled states.
- Always request a press proof when using CMYK conversions from RGB — screen-to-print color matching requires a device color profile.
- Use the browser color picker to sample colors directly from screenshots or design assets — no need to copy values manually.
- After converting, test your colors in a contrast checker to confirm your palette meets WCAG AA (4.5:1) for body text.
- Store your brand palette in all formats (HEX, RGB, CMYK) in your design system documentation to eliminate repeated conversions.
Why Accurate Color Conversion Matters
- Inconsistent color values across design and development teams are one of the leading causes of visual inconsistency in shipped products.
- RGB and CMYK occupy different gamuts — colors that look vibrant on screen can appear muddy in print without a proper conversion.
- CSS HSL makes dynamic theming (light/dark mode, tints) far easier than HEX — but requires accurate HEX-to-HSL conversion to start.
- Brand compliance audits require colors in multiple formats — a single converter eliminates manual errors and saves hours of back-and-forth.
Performance & Privacy
Every color conversion runs entirely within your browser using vanilla JavaScript. No color value, palette, or usage data is ever sent to any server. The tool responds in under 10 ms per conversion, works offline after the first visit, and requires no account or registration.
Educational Note: Color Spaces Explained
RGB (Additive)
RGB mixes red, green, and blue light. All channels at 255 = white; all at 0 = black. Used by screens, cameras, and web browsers.
HEX (Web Shorthand)
HEX is RGB encoded as base-16. #3b82f6 = R:59, G:130, B:246. It is identical to RGB — just a more compact notation for CSS and HTML.
HSL (Perceptual)
HSL separates hue (color wheel angle 0–360°), saturation (intensity), and lightness (brightness). Easier to reason about than RGB for designers.
CMYK (Subtractive)
CMYK mixes Cyan, Magenta, Yellow, and Key (black) ink. It subtracts from white paper. Screen RGB has a wider gamut — some bright RGB colors cannot be reproduced in CMYK.
Troubleshooting
Did You Know?
HEX color notation was introduced to HTML in 1996 with the HTML 3.2 specification. Before that, browsers only recognised 16 named colors (like "red" and "blue"). The full web color palette expanded to 140 named colors with CSS1, but HEX remained the dominant format — and still is, more than 25 years later.
