Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00207 | $0.02947 |
| Opus 5.5 | $0.00083 | $0.01179 |
| Sonnet 5.5 | $0.00041 | $0.00589 |
| Haiku 4.5 | $0.00021 | $0.00295 |
Grade A, and why
openclaw-color-palette scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

OpenClaw Color Palette v2.0
Design-grade color tools -- 5 tools for palettes, accessibility, conversion, simulation, and extraction.
Quick Reference
| Situation | Action | Tool |
|---|---|---|
| Starting a new website or app design | Generate a harmonious palette from a brand color | generate_palette |
| Text looks hard to read on a background | Check WCAG 2.1 AA/AAA contrast ratio | check_contrast |
| Designer gave hex, you need RGB for code | Convert between any color format | convert_color |
| Need to ensure inclusive design | Simulate 8 types of color vision deficiency | color_blindness_sim |
| Client sent a logo, need brand colors | Extract dominant colors with frequency data | extract_palette |
| Building a design system from scratch | Generate palette + check contrast + simulate CVD | All 3 combined |
What's New in v2.0
- :art: HarmonyEngine -- 6 color theory algorithms: complementary, analogous, triadic, split-complementary, tetradic, monochromatic. Mathematically precise palette generation from any seed color.
- :shield: AccessGuard Protocol -- Full WCAG 2.1 AA and AAA checking for normal and large text. When contrast fails, auto-suggests the nearest accessible color pair with minimal visual change.
- :eye: VisionSim 8-Type -- Simulate protanopia, deuteranopia, tritanopia, achromatopsia, protanomaly, deuteranomaly, tritanomaly, and achromatomaly. Warns when palette colors become indistinguishable.
- :dropper: ChromaExtract -- K-means clustering extracts 5-10 dominant colors from any image URL or base64 data, sorted by area percentage.

Detection Triggers
This skill activates when you say:
- "generate a color palette" / "color scheme for my website" / "give me colors for"
- "check contrast" / "is this readable" / "WCAG accessibility" / "contrast ratio"
- "convert hex to RGB" / "convert color" / "what is #FF5733 in HSL" / "hex to CMYK"
- "simulate color blindness" / "how do colorblind users see this" / "protanopia simulation"
- "extract colors from image" / "pull palette from logo" / "brand colors from screenshot"
- "complementary colors" / "analogous palette" / "triadic" / "split-complementary" / "monochromatic"
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openclaw-color-palette is a skill published in the GitHub repository yedanyagamiai-cmd/openclaw-mcp-servers (4 stars, last pushed 7mo ago), licensed MIT. It adds 207 tokens to every session and 2,947 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
html-design-revision
Revise an existing HTML/CSS design file with small, safe edits. Use when asked to change a color, text, size, position or add an element to a design that already exists. Use other tools for building a design from scratch.
html-author
Build a finished one-page or multi-page design (flyer, letterhead, handout, deck, poster, menu, card, report, invoice) as a single HTML/CSS file at a fixed pixel size. Use when asked to design something from a brief, starting from nothing. Use other tools to edit an existing file.
site-header
Design and build the site-wide header (logo, menu, language switcher, cart, call to action) yourself, then have the site save it in the right places and check it. Activate whenever the user asks to create, fix, redesign, modernise, tidy or "make professional" a header or top navigation, or complains that the menu…
section-rebuild
Build a page section in code using the values measured off a real site rather than guessing them from a screenshot. Use when the user wants to recreate, adapt or take inspiration from a hero, pricing table, FAQ, testimonial or any other section they have seen.
block-theme
Change a block theme's look and structure the way the site editor does - Global Styles (colours, fonts, spacing), templates and template parts (header, footer, single, page), patterns and navigation menus - with undo. Activate when the user asks to change site-wide colours or fonts, edit the header, footer or a page…
builder-quality
Check that an Elementor page an agent built or changed is easy for a person to edit afterwards - no layout pasted into HTML widgets, no inline styles or scripts, global colours instead of fixed ones, sensible nesting - and fix what it finds. Activate after building or redesigning an Elementor page, or when the user…
