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 | $0.00103 | $0.01473 |
| Sonnet 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 12d 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.

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 (3 stars, last pushed 5mo ago), licensed MIT. It adds 207 tokens to every session and 2,947 once invoked, about $0.0010 per session on Opus 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.
