Color Palette
Extract dominant colors from a photo and get HEX/RGB values for use in design tools or mood boards.
Dependencies
Pillow (image handling; required) colorgram (optional; better dominant-color extraction; pip install colorgram.py) matplotlib (optional; only if generating swatch image with --output) Setup: OpenClaw does not install Python packages automatically. After installing this skill, run once: pip install -r requirements.txt (from the skill folder or pass the path). If a script fails with ModuleNotFoundError, install the missing package.
Extract palette from an image
Parameters: image: Path to the image file (JPEG, PNG, etc.). -n, --num-colors: Number of colors to extract (default 5, max 20). --output: Optional path to save a swatch PNG. python3 scripts/extract_palette.py /path/to/photo.jpg python3 scripts/extract_palette.py /path/to/photo.jpg -n 8 --output palette_swatch.png Output: one line per color with HEX and RGB (e.g. #2A4B7C RGB(42, 75, 124)). If --output is set, a simple swatch image is saved.
Sending images to Telegram
These skills are used from the OpenClaw Telegram conversation. To show the user a picture, the agent must (1) run the script with an image output path (PNG or JPG), then (2) send that file to the conversation using the OpenClaw message/media tool. For this skill: use --output <path>.png so you have an image to send; then send that PNG to the user. OpenClaw allowed paths: The message tool only sends files from allowed dirs (~/.openclaw/media/, ~/.openclaw/agents/, or system temp e.g. /tmp). Use e.g. --output ~/.openclaw/media/palette.png or --output /tmp/palette.png; do not use the skill install directory or sending will fail. Agent behavior: When the user asks to extract colors from an image (or sends an image for a palette), run the script directly with exec: save the image to a temp path if needed, run extract_palette.py <image_path> -n <N> --output <path>.png with <path> under an allowed dir, return the HEX/RGB text and send the swatch PNG. Do not ask for confirmation; execute and return the palette and image.
Examples
User: "Extract 5 colors from this image" (with image attached). Action: Save the image to a temp path, run extract_palette.py <path> -n 5 --output /tmp/palette.png, return the HEX/RGB list and send the swatch PNG. User: "Give me a color palette from [image] and save the swatch as swatch.png." Action: Run with --output swatch.png, return the palette text and send the image.
