What Are Web-Safe Colors?
In the early era of the World Wide Web, computer monitors were limited to an 8-bit color depth capable of displaying only 256 simultaneous colors. Computer operating systems reserved 40 system colors, leaving a standardized pool of 216 web-safe colors. These colors are mathematically generated using six distinct values for each RGB channel: 00, 33, 66, 99, CC, FF (or decimal 0, 51, 102, 153, 204, 255).
The 6×6×6 Color Cube
Because 6 levels of Red × 6 levels of Green × 6 levels of Blue equals 216, these colors form a perfect geometric cube within the sRGB coordinate system.
Zero Dithering Artifacts
Any computer screen displaying web-safe colors renders solid, uniform fills without needing checkerboard dithering patterns or color approximations.
Retro & Pixel Art Design
Modern developers and digital artists frequently use the 216 palette to craft nostalgic early-2000s aesthetics, pixel art sprites, and vintage software UIs.
Universal Hardware Compatibility
Supported natively across every operating system, terminal emulator, digital watch, and embedded display without requiring modern color profile support.
Frequently Asked Questions
Are web-safe colors still relevant today?▼
Modern displays support 24-bit True Color (16.7 million colors) or even 30-bit HDR (over 1 billion colors), so web-safe colors are no longer a strict technical requirement. However, they remain a beloved curated palette for minimalist UI components, data visualization categories, and retro design themes.
