Color Converter — Convert Between HEX, RGB, HSL, CMYK & More

Convert between all color formats simultaneously. Change any value and every other format updates in real-time. HEX, RGB, HSL, HSV, CMYK, CSS variables.

All Color Formats in One Tool

Different tools and platforms use different color formats. CSS uses HEX, RGB, and HSL. Figma and Photoshop show HSB/HSV. Print designers need CMYK. Instead of juggling multiple converter tools, this single interface shows every format simultaneously and lets you edit any one — all others update instantly.

When to Use Each Format

HEX: Web design, CSS, HTML, brand guidelines. RGB: Screens, digital design, JavaScript canvas. HSL: Intuitive color manipulation, creating tints/shades. HSV/HSB: Design tools (Photoshop, Figma). CMYK: Print design (approximate without ICC profiles).

Real-Time Bidirectional Conversion

Every input field is both readable and editable. Type a HEX code and see the RGB, HSL, HSV, and CMYK values appear. Adjust the HSL lightness slider and watch the HEX code change. Pick a color visually and all numeric values update. This bidirectional approach means you can work in whichever format is most natural for your task.

Frequently Asked Questions

How do I convert HEX to RGB?▼
Paste or type your HEX code (like #3B82F6) into the HEX field and the RGB values appear instantly — R: 59, G: 130, B: 246. The first two hex characters are red, the middle two are green, the last two are blue.
What is a WCAG contrast ratio and why does it matter?▼
The WCAG contrast ratio measures how distinguishable two colors are, from 1:1 (no contrast) to 21:1 (maximum). WCAG 2.1 requires a minimum of 4.5:1 for normal text (AA) and 7:1 for the highest standard (AAA). This ensures people with visual impairments can read your content.
What’s the difference between RGB and HSL?▼
RGB defines colors by mixing red, green, and blue light (0-255 each). HSL describes colors as Hue (color wheel position 0-360°), Saturation (vividness 0-100%), and Lightness (brightness 0-100%). HSL is more intuitive for creating color variations.
Is CMYK conversion accurate?▼
Our CMYK conversion is mathematically correct but approximate. Precise CMYK values for print depend on ICC color profiles. Our conversion uses the standard formula, sufficient for digital mockups. For production print, use your print provider’s color profile.
Can I extract colors from an image?▼
Yes. Upload any image and click anywhere on it to pick a pixel’s color, or let the tool extract the 5-6 most dominant colors automatically. The image is processed entirely in your browser — never uploaded to any server.
What color format should I use for web design?▼
For CSS, HEX (#3B82F6) and RGB are both widely supported. HSL is increasingly preferred because it’s easier to create color variations. For opacity, use RGBA or HSLA. Tailwind CSS uses predefined color classes like bg-blue-500.
How does the palette generator work?▼
It uses color theory to find harmonious combinations. From your color’s hue on the color wheel, it calculates complementary (180° opposite), analogous (nearby), triadic (120° apart), and other harmonies. These mathematical relationships produce colors that naturally look good together.
Is my data private?▼
Nothing leaves your browser. All color calculations, conversions, and image processing happen entirely in JavaScript on your device. No data is stored on any server.
