How do I convert RGB to HEX?

Enter your R, G, B values (0-255 each) into the RGB fields. The HEX code appears instantly. Each value is converted to a two-digit hexadecimal number.

RGBA adds an alpha (opacity) channel. The alpha value (0-1) converts to a two-digit hex appended to the 6-digit code, creating an 8-digit hex like #FF000080 (red at 50% opacity).

Why use HEX over RGB in CSS?

HEX codes are shorter (#3B82F6 vs rgb(59, 130, 246)), widely recognized, and easier to copy-paste. Both are valid in CSS and produce identical results.

Enter R, G, B values (0-255 each) and get the HEX color code instantly. Also converts RGBA with opacity to 8-digit hex.

Why Convert RGB to HEX?

HEX codes are the most common way to specify colors in web design. They're compact (#3B82F6 vs rgb(59, 130, 246)), universally recognized by designers and developers, and the standard format in brand guidelines, Figma, Sketch, and CSS.

The Conversion Process

Each RGB value (0-255) maps to a two-digit hexadecimal number (00-FF). R: 59 becomes 3B, G: 130 becomes 82, B: 246 becomes F6. Combine them with a # prefix: #3B82F6. For RGBA, the alpha value (0-1) is multiplied by 255 and appended as two more hex digits.

Using HEX Codes in Web Design

In CSS: color: #3B82F6; or background-color: #3B82F6;. In HTML email templates, HEX is often the only reliable format. In design tokens and CSS custom properties: --primary: #3B82F6;. Tailwind CSS maps its color classes to HEX values internally.

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.
