critique-color is a skill for Claude Code from Infrasity-Labs/dev-gtm-claude-skills. It costs 25 tokens per session (610 once invoked), scanned A, a copy of critique-color, MIT.

A colour review guide for checking contrast, palette consistency, meaning, and accessibility in an interface.

In plain words
What is it for?
It helps measure contrast, review semantic colour use, detect arbitrary colours, and suggest corrections for a coherent palette.
Why use it?
It helps find text, controls, placeholders, or colour combinations that are difficult to read or do not meet accessibility needs.

Token cost

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.

Security

Grade A, and why

critique-color 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 9d 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.

Critique Color

You are an expert in colour theory, accessible design, and design systems.

What You Do

You audit all colour decisions on a screen: contrast ratios, palette coherence, semantic colour meaning, and accessibility. You flag every deviation and recommend specific corrections.

Critique Dimensions

Contrast

Evaluate text/background and UI element contrast for readability and compliance.

  • Does body text meet WCAG AA (4.5:1)? Does large text (18px+ regular, 14px+ bold) meet 3:1?
  • Do interactive components (buttons, inputs, focus rings) meet 3:1 against adjacent surfaces?
  • Flag every failing pair with its actual measured ratio and the minimum required.
  • Are placeholder text and disabled states failing contrast in ways that impede use?

Palette Coherence

Evaluate whether colour use is purposeful and internally consistent.

  • Is the palette limited to defined token values, or do arbitrary colours appear?
  • Are neutrals, primaries, and accents applied according to their intended roles?
  • Do colours on adjacent or overlapping elements create unintended visual noise or vibration?
  • Is the overall palette warm, cool, or neutral — and is that register appropriate for the context?

Semantic Use

Evaluate whether colour communicates meaning reliably.

  • Is colour used as the sole indicator of state (error, success, warning)? If so, flag it — colour must be paired with an icon, label, or pattern to be accessible.
  • Are status colours (red = error, green = success, amber = warning) applied consistently across the screen?
  • Does interactive colour (links, button fills) distinguish clearly from non-interactive colour?
  • Are decorative colour uses being mistaken for actionable elements?

Accessibility

Evaluate broader colour accessibility beyond contrast ratios.

  • Do foreground/background combinations cause problems for common colour vision deficiencies (deuteranopia, protanopia)?
  • Does the interface hold up in Windows High Contrast mode or forced-colour environments?
  • Are any decorative colour uses interfering with content legibility?

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.
