The 16 standard web colors are predefined color names that are recognized by all major web browsers. These colors allow web developers and designers to specify colors on a web page without having to use hex or RGB values. The 16 colors were originally defined in the HTML 3.2 specification in 1996 as part of the X11 color system. They have become a standard part of CSS and HTML.
History of the 16 Web Colors
The first web browsers could only display a limited palette of colors. In the early 1990s, Tim Berners-Lee, the inventor of the World Wide Web, created a list of just 16 colors that all web browsers should support. This list became known as the X11 colors or the 16 basic HTML colors.
The X11 color names and hex values were defined in the X Window System used by Unix computers in the 1980s. The web incorporated these same 16 colors to ensure cross-browser compatibility. By standardizing on this small set of colors, Berners-Lee helped ensure that early web pages would look consistent on different browsers and platforms.
The 16 original HTML colors were:
| Color Name | Hex Value |
| Black | #000000 |
| Green | #008000 |
| Silver | #C0C0C0 |
| Lime | #00FF00 |
| Gray | #808080 |
| Olive | #808000 |
| White | #FFFFFF |
| Yellow | #FFFF00 |
| Maroon | #800000 |
| Navy | #000080 |
| Red | #FF0000 |
| Blue | #0000FF |
| Purple | #800080 |
| Teal | #008080 |
| Fuchsia | #FF00FF |
| Aqua | #00FFFF |
These original colors were chosen to be easy to distinguish, even on low-quality displays. They ensured readable text and provided enough variety for simple colorful designs.

Usage of the 16 Colors
The 16 web colors provide a basic color palette for any website or HTML project. Here are some examples of how these standard colors get used:
- Black and white both make ideal page backgrounds to set the tone.
- Grays create subtle backgrounds that don’t distract from text-heavy content.
- Maroon, red, and purple add vibrancy for headings and buttons.
- Green and lime allow call-to-action buttons to stand out.
- Blue variations like navy and aqua convey professionalism and calmness.
- Neutral browns like olive complement natural color schemes.
The 16 original web colors can be combined to generate most hues. For example, purple combines red and blue. Teal mixes green and blue. Designers use these primary colors as the basis for entire color schemes.
While millions of additional colors are now supported in modern browsers, these 16 remain the most widely recognized. Their names ensure colors display consistently across all platforms without using hex or RGB values.
Current Status of the 16 Web Colors
The 16 original HTML colors are now a legacy feature of web design. Modern browsers support millions of colors, allowing for more advanced and nuanced palettes. But the original 16 retain their importance:
- All major browsers still recognize the color names for backward compatibility.
- The colors ensure plain text remains readable in email clients and other applications.
- Designers use the colors as common reference points between projects.
- The colors provide a basic starting palette for new sites and themes.
- Web development courses continue teaching the significance of the 16 colors.
While advanced CSS3 techniques allow for color gradients, shadows, animation, and more – the fundamental 16 colors remain relevant in web design.
Conclusion
The 16 basic web colors have defined the appearance of websites since the earliest days of the internet. These 16 colors were originally chosen for maximum readability on low-resolution displays. As bit-depth grew over time, millions of colors became usable in web pages.
But the original color palette remains a core part of HTML and CSS specifications. All browsers still recognize the 16 color names for backward compatibility. These colors form the basis for accent colors, backgrounds, text, and more on many websites. Their hex codes and RGB values are also commonly used as reference points in design software.
So while expanded color options allow for far more creativity, the 16 original colors continue to have an important place on the web. They ensured text readability and visual consistency in the past. And they continue providing a common framework and legacy support moving forward.
