HTML Color Names Reference

HTML color names are predefined keywords that represent specific colors in web development. Originally specified in the HTML 4.01 standard with 16 basic colors (aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow), the list was expanded in CSS Color Module Level 3 to include 147 additional named colors, bringing the total to 147. CSS Color Level 4 later added rebeccapurple, honoring Eric Meyer's daughter, bringing the total to the current 148 named colors.

Unlike hexadecimal or RGB color codes, named colors are intuitively readable and memorable. Using coral instead of #FF7F50 makes your CSS more descriptive and maintainable, especially when working in teams or when semantic color naming is important for design system consistency.

Our HTML Color Names Reference organizes all 148 named colors into a searchable, filterable grid that makes finding the right color quick and intuitive. Here is how it works:

1. Browse or search - Scroll through the complete color grid or type a name (like "coral" or "rebeccapurple") or a HEX value (like #FF7F50) into the search bar. The results update in real time as you type, showing matching colors instantly.
2. Filter by category - Use the category chips to narrow down results: view only the 16 standard HTML 4.01 colors, the extended CSS named colors, or just the colors that are safe to use in HTML emails. Each filter helps you find colors suited to specific use cases.
3. Copy and use - Each color card includes copy buttons for both the color name and HEX value. Click to copy, then paste directly into your CSS, HTML, email template, or design tool. The visual swatch gives you an accurate preview of how the color looks.

• Browser Support: All 148 CSS named colors are supported in every modern browser - Chrome, Firefox, Safari, Edge, and Opera. The 16 basic HTML 4.01 colors are supported in virtually every browser ever created, including Internet Explorer 3+. Extended CSS named colors are supported in all CSS3-capable browsers (IE 9+).
• Email Client Compatibility:The 16 standard HTML 4.01 colors, plus a few commonly used extended colors like orange, brown, pink, and gold, are widely supported across all email clients including Outlook (desktop and web), Gmail, Yahoo Mail, and Apple Mail. More obscure extended colors may not render correctly in Outlook's Word-based rendering engine and may fall back to a default color.
• Web-Safe Colors:Colors marked as "Web Safe" are among the 216 colors that display consistently across all monitors and browsers without dithering. While less critical with modern displays, web-safe colors are still useful for maintaining consistent appearance across older or lower-quality screens.
• CSS Color Level 4: The modern CSS Color Level 4 specification introduced rebeccapurple(hex #663399) in 2014, honoring Eric Meyer's daughter Rebecca. This is the most recently added named color and is supported in all modern browsers.
