Most modern computer displays can display up to 16 million colors, but to ensure that your web design works well for the widest possible audience, consider limiting your color choices to the 216 safe HTML colors.  These "browser-safe" colors are designed to display accurately by all web browsers, without dithering, even on 256 color displays.

Safe HTML Colors and their RGB Values
216 Web-Safe Colors with their RGB Values

During the mid-1990s, when most personal computers could display only 256 different colors, the Microsoft Windows and Apple Macintosh operating systems each reserved about 20 different system colors, leaving about 216 remaining colors for user applications.  So a set of 216 Web Safe Colors was suggested as a World Wide Web standard.  This 216 color palette is designed into popular graphics software such as Photoshop, Illustrator, and GoLive as well as Dreamweaver and Paint Shop Pro.

Most computers today can display millions of different colors, so these 216 Web Safe Colors are not as important as they were 10 years ago.  However, many Internet-capable cell phones and PDAs now have 256 color displays, so it is still a good idea to use these colors where possible.

The HTML Color swatch tool is designed to help you work with these 216 Web Safe Colors exclusively.  Below is a simplified version of this tool.  Simply click any cell below to display a movable, resizable swatch of the indicated color.
