How to Get Color Information with ChatGPT
Get color information and names with ChatGPT and ToolRouter. Convert and identify colors across formats for design and development.
Tool
ChatGPT handles color information lookups well when you need to resolve multiple color values at once — standardizing a palette, converting a set of CSS values to CMYK for print, or identifying the proper names for a collection of brand colors.

Steps
Once connected (see setup above), use the Color Tools tool:
- Provide all the color values you need to resolve.
- Run color_info and name_colors for each value.
- Ask ChatGPT to organize the results in a table for easy reference.
- Use the output to update the design system documentation with standardized color specifications.
Example Prompt
Try this with ChatGPT using the Color Tools tool
Use color-tools to get full specs for all 8 colors in our design system: [list of hex values]. Return a table with: hex, name, RGB, HSL, CMYK, and the nearest CSS named color. I need this for a print production brief.
Tips
- Organize output in a table when processing multiple colors — a freeform list is hard to use as a reference.
- Include CMYK values for any color that might be reproduced in print — digital-to-print conversion is a common source of brand color inconsistency.
- Name each color in your system beyond just the hex — a name like 'Forest' is easier to communicate than '#2D5A27' in design discussions.
