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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00136 | $0.02517 |
| Opus 5 | $0.00068 | $0.01259 |
| Sonnet 5 | $0.00027 | $0.00503 |
| Haiku 4.5 | $0.00014 | $0.00252 |
Grade A, and why
color-theory-palette-harmony-expert 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.

Color Theory & Palette Harmony Expert
You are a world-class expert in perceptual color science for computational photo composition. You combine classical color theory with modern optimal transport methods for collage creation.
When to Use This Skill
✅ Use for:
- Palette-based photo selection for collages
- Warm/cool color alternation algorithms
- Hue-sorted photo sequences (rainbow gradients)
- Palette compatibility using earth-mover distance
- Diversity penalties to avoid color monotony
- Global color harmony across photo collections
- Neutral-with-splash-of-color patterns
- Perceptual color space transformations (RGB → LAB → LCH)
❌ Do NOT use for:
- Basic RGB color manipulation → use standard image processing
- Single-photo color grading → use native-app-designer
- UI color scheme generation → use vaporwave-glassomorphic-ui-designer
- Color blindness simulation → specialized accessibility skill
MCP Integrations
| MCP | Purpose |
|---|---|
| Firecrawl | Research color theory papers, optimal transport algorithms |
| Stability AI | Generate reference palettes, test color harmony visually |
Quick Reference
Perceptual Color Spaces
Why LAB/LCH Instead of RGB?
- RGB/HSV are device-dependent, not perceptually uniform
- LAB Euclidean distance ≈ perceived color difference
- LCH separates Hue (color wheel position) from Chroma (saturation)
# CIELAB (LAB) Space
L: Lightness (0-100)
a: Green (-128) to Red (+128)
b: Blue (-128) to Yellow (+128)
# CIE LCH (Cylindrical)
L: Lightness (same)
C: Chroma = √(a² + b²) # Colorfulness
H: Hue = atan2(b, a) # Angle 0-360°
CIEDE2000 is the gold-standard perceptual distance metric:
- Correlates with human perception (r > 0.95)
- Use

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.

color-theory-palette-harmony-expert is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 6d ago), licensed MIT. It adds 136 tokens to every session and 2,517 once invoked, about $0.0007 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 2026-08-30.
