Steps
Once connected (see setup above), use the Color Tools tool:
- Provide the color value in any format — hex, RGB, or HSL — and describe what you need to know about it.
- Run color-tools with color_info and name_colors for the target color.
- Ask Claude to explain the color's relationships — complement, analogous neighbors, and which combinations would create the visual tension or harmony you are after.
- Use the information to inform color pairing decisions or convert to the format needed for the project.
Example Prompt
Try this with Claude using the Color Tools tool
Use color-tools to get full information on #FF6B35 — name, all format conversions (hex, RGB, HSL, CMYK), complementary color, and three analogous colors. Tell me what mood this color creates and what type of brand identity it would suit well.
Tips
- Ask Claude to explain the color's emotional associations alongside the technical values — both are useful for design decisions.
- Get the CMYK values whenever you are doing anything that might go to print — digital hex codes do not translate directly.
- Ask for the color name as well as the hex — named colors are easier to reference in documentation and discussion.
