Colormind (Color Palette Generator)

⚠️ Privacy & Security Notice:

This skill sends color data to an external service (colormind.io)
The API uses unencrypted HTTP (HTTPS has a self-signed certificate)
When using image_to_palette.sh, derived color data from your images is sent externally
Do not use with sensitive/private images unless you accept this data sharing
Consider running in a sandbox when processing untrusted images (ImageMagick safety)

Colormind exposes a simple API:

POST http://colormind.io/api/ → generate a palette (optionally with locked colors)
GET http://colormind.io/list/ → list available models

List models

bash

node {baseDir}/scripts/list_models.mjs

Generate a random palette

bash

node {baseDir}/scripts/generate_palette.mjs --model default
node {baseDir}/scripts/generate_palette.mjs --model ui

Generate a palette with locked colors

Provide 5 slots. Use:

an RGB triple: "r,g,b" (locks that slot)
N (free slot)

Examples:

bash

# lock 2 colors, let colormind fill the rest
node {baseDir}/scripts/generate_palette.mjs --model default \
  --input "44,43,44" "90,83,82" N N N

# lock a brand color, keep a free gradient
node {baseDir}/scripts/generate_palette.mjs --model ui \
  --input "0,122,255" N N N N

Output:

always prints JSON
if --pretty is set, also prints a small Markdown block (hex + RGB)

bash

node {baseDir}/scripts/generate_palette.mjs --model default --pretty

Sample an image → get a palette

Requires ImageMagick (convert). This samples a small palette from an image, picks the most frequent color as the "base", then generates a Colormind palette from it.

bash

# returns JSON with sampled colors + a generated Colormind palette
bash {baseDir}/scripts/image_to_palette.sh /path/to/image.jpg --model ui
bash {baseDir}/scripts/image_to_palette.sh /path/to/image.jpg --model default

Notes:

Colormind may slightly adjust locked colors.
Models refresh daily (UTC+8).

Installation

Terminal bash


openclaw install colormind
