Common Use Cases

CSS development

Quickly convert a design tool's CMYK or HSL color to HEX or RGB for use in your CSS stylesheet or Tailwind config.

Print design

Convert hex colors from your web design to CMYK values required by your print shop or InDesign/Illustrator project.

Design handoff

When handing off designs to developers, provide both HEX (for CSS) and RGB (for iOS/Android) values from the same source color.

Accessibility checks

Convert colors to understand their lightness values in HSL — useful for checking WCAG contrast ratios between text and backgrounds.

How do I convert HEX to RGB?

Remove the # symbol. Split the 6-character hex code into three 2-character pairs. Convert each pair from hexadecimal (base 16) to decimal (base 10): #3b82f6 → 3b=59, 82=130, f6=246 → rgb(59, 130, 246). For shorthand 3-digit hex (#abc), expand each digit: #abc = #aabbcc. This tool converts HEX to RGB (and all other formats) automatically as you type.

What are the RGB and HEX values for black and white?

Black: #000000 · rgb(0, 0, 0) · hsl(0, 0%, 0%) · cmyk(0%, 0%, 0%, 100%). White: #ffffff · rgb(255, 255, 255) · hsl(0, 0%, 100%) · cmyk(0%, 0%, 0%, 0%). Pure red: #ff0000 · rgb(255, 0, 0). Pure green: #00ff00 · rgb(0, 255, 0). Pure blue: #0000ff · rgb(0, 0, 255).

When should I use CMYK instead of RGB?

Use CMYK for anything going to print — brochures, business cards, posters, packaging. CMYK represents how physical inks mix (subtractive color). Use RGB for anything displayed on screens — websites, apps, digital ads, presentations. When RGB colors are converted to CMYK for print, vivid RGB colors (especially neon and saturated blues) often appear duller because CMYK gamut is smaller than RGB.

Frequently Asked Questions

What is the difference between HEX, RGB, and HSL?+
HEX is a 6-digit hexadecimal representation used in CSS and HTML (#ff5733). RGB defines color as Red, Green, Blue values (0–255). HSL defines color as Hue (0–360°), Saturation (0–100%), and Lightness (0–100%) — more intuitive for adjusting colors.
When should I use CMYK?+
CMYK (Cyan, Magenta, Yellow, Key/Black) is used in print design and physical color printing. When preparing files for commercial printing, use CMYK values to ensure accurate color reproduction.
Can I enter any color format to start the conversion?+
Yes. Type into any of the four fields — HEX, RGB, HSL, or CMYK — and all other fields will update automatically in real time.
Does the color picker work on mobile?+
Yes. The native color picker input works on iOS and Android browsers, giving you access to your device's color picker to select any color.
