Palette

The Palette tab is a small color theory tool. Pick a base color, choose a harmony scheme, generate a lightness ramp, copy individual swatches or export the whole set.

Open it

Title bar Tools menu, then Pipeline tools, then Palette.

Inputs

• Base color. Hex picker plus a text input. Validates #RRGGBB.
• Harmony. One of:
  • Mono (single hue, varied lightness).
  • Complementary (base plus its opposite).
  • Split-comp (base plus the two adjacent to its complement).
  • Triad (three colors evenly spaced on the wheel).
  • Tetradic (two complementary pairs).
  • Analogous (three adjacent hues).
• Ramp steps. Number of lightness steps from black to white through the base. Slider, 3 to 11.

The harmony swatches and the lightness ramp render below as separate grids.

Click a swatch

Clicking any swatch copies its hex value to the clipboard. A “copied” toast confirms. If your browser doesn’t grant clipboard access, the copy silently fails; you can still select the hex from the export pane below.

Export

Three formats:

• Hex list. One color per line, no prefix. Useful for piping into scripts.
• CSS variables. --color-1: #...; declarations.
• GIMP / Aseprite (.gpl). GIMP Palette Format, also accepted by Aseprite.

The preview pane shows the export text. Hit Copy to grab it, or Save… to write a file.

Output

Files save to <project>/.forge/generated/palettes/<timestamp>.<ext>. The extension matches the format you exported.

Notes

• The base color defaults to Forge’s brand persimmon #a35a3c. Change it once and your future generations start from there.
• Duplicate colors in the export are removed by hex value (case-insensitive). If your harmony naturally produces a near-duplicate, you’ll see one entry, not two.
• This tool runs entirely in your browser. No external API. No key required.
