Web-Safe Color Palette
Browse the classic 216 web-safe colors as a clickable swatch grid — sort by hue or cube order, filter by hex, and copy any HEX or rgb() value instantly.
The 216 web-safe colors are every combination of the levels 00, 33, 66, 99, CC and FF on each RGB channel. Everything runs in your browser — no uploads, no sign-up, completely free.
About Web-Safe Color Palette
The web-safe color palette is the classic set of 216 colors built from the six RGB channel levels 00, 33, 66, 99, CC and FF — the 6×6×6 color cube that early displays could render without dithering. This tool lays out all 216 swatches in one clickable grid so you can scan, compare and grab any value in seconds.
You can view the palette in its original cube order or re-sort it by hue, which groups grays first and then walks through the spectrum. A hex filter box narrows the grid as you type, so entering 33CC jumps straight to the swatches that start with those digits.
Clicking a swatch copies its HEX code immediately and opens a detail panel with the matching rgb() value and the nearest named CSS color, each with its own copy button. Everything is computed in your browser, which makes it a quick reference for retro palettes, email-safe colors and constrained design systems.
How to use Web-Safe Color Palette
- Open the tool to see all 216 web-safe colors as a swatch grid, sorted in cube order by default.
- Switch the sort order to “By hue” if you would rather browse grays first and then colors grouped along the spectrum.
- Type into the hex filter box (for example 33CC99) to narrow the grid to swatches whose HEX code starts with those characters.
- Click any swatch — its HEX value is copied to your clipboard right away and a detail panel opens below the grid.
- Use the copy buttons in the detail panel to grab the HEX code, the rgb() value or the nearest named CSS color.
