Generate Brand Color Palettes
Create cohesive color palettes for brand identities, websites, and design systems — from a seed color or a descriptive prompt.
Get Color Information and Names
Look up detailed information about any color — name, hex, RGB, HSL, CMYK values, and complementary colors — for design and development use.
Quick answer: Use the Color Tools tool through ToolRouter to get color information and names directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolWorking across design tools, development environments, and print production constantly requires translating colors between formats — hex to RGB for CSS, RGB to CMYK for print, or just figuring out what a color is called so you can reference it consistently in design documentation.
Color Tools' color_info and name_colors skills provide complete color information in one step — converting between all color models, returning the closest named color, showing complementary and analogous relationships, and giving you everything you need to specify the color accurately in any context.
Developers who need CSS-ready color values, designers working across digital and print who need CMYK conversions, teams trying to name and standardize their color system, and anyone who has ever copied a hex code from a screenshot and needed to know what it actually is use this to get complete color information without tab-switching between converter tools.
How to get color information and names with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude is the right partner for color information lookups when you want to understand the color relationships — what the complement is, where it sits on the color wheel, and whether there are other colors in the same family that might serve your design better.

How to get color information and names with Claude
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 for Claude
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 for Claude
- 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.
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.

How to get color information and names with ChatGPT
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 for ChatGPT
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 for ChatGPT
- 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.
Copilot is best for color information lookups when the results need to be embedded directly in a design spec, print brief, or developer handoff document as part of the production workflow.

How to get color information and names with Copilot
Once connected (see setup above), use the Color Tools tool:
- Provide the color values and the document context they need to appear in.
- Run color_info and name_colors for each color.
- Format the complete specification for each color and insert it into the document.
- Confirm the CMYK values are included if any colors will be used in print production.
Example prompt for Copilot
Try this with Copilot using the Color Tools tool
Use color-tools to get complete specifications for our primary brand color #1A3C5E. Return: color name, hex, RGB, HSL, CMYK, and nearest CSS named color. Format it as a color specification entry for our brand guidelines document.
Tips for Copilot
- Include all format conversions in the brand guide — different teams use different tools that require different formats.
- Add a 'print note' to any color with a CMYK equivalent that looks noticeably different from the digital hex.
- Version the color specifications in the guide — 'Brand Blue v1.0' — so you can track changes over time.
OpenClaw handles color information resolution at scale — processing an entire design system's worth of colors, converting a client's multi-brand color library, or standardizing color values across a large codebase.

Once connected (see setup above), use the Color Tools tool:
- Define all colors to process and the output format needed.
- Run color_info and name_colors across all colors.
- Organize the complete color library by brand, palette, or design token category.
- Export as a structured reference document ready for use in design tools and documentation.
Example prompt for OpenClaw
Try this with OpenClaw using the Color Tools tool
Use color-tools to resolve full specifications for all 35 colors in our design token library. Return each with: token name, hex, RGB, HSL, CMYK, CSS name, and accessibility note. Organize by token category (brand, semantic, neutral) in a table format.
Tips for OpenClaw
- Organize by token category from the start — a flat list of 35 colors is harder to use than a structured system.
- Include a brief accessibility note for each color indicating whether it should be used for text or backgrounds.
- Export as a CSV or structured document so the design system team can import the data directly into their tooling.
