Web Safe Colors Palette
Browse the standard 216 web-safe colors. Our free utility provides an interactive, offline-capable palette to ensure your legacy UI designs render perfectly across all monitors.
What is the Web Safe Colors Palette?
In the early days of the internet, most computer monitors could only display 256 colors, and operating systems reserved 40 of them. This left a specific set of 216 'web-safe' colors that were guaranteed to display identically across Windows and Mac environments without 'dithering' (ugly pixelation). While modern 4K monitors can display millions of colors, adhering to the 216-color palette is still highly useful for retro UI design, HTML email templates, and ensuring absolute cross-compatibility on low-end industrial displays. This tool provides a clean, local grid of the exact CSS hex codes.
