color-principles

color-principles is a skill for Claude Code, Codex from aka-kika/akakika-skills. It costs 52 tokens per session (497 once invoked), scanned A, original, MIT.

A set of seven guidelines for choosing and applying interface colours. It covers palette size, muted tones, text contrast, accent colours, near-black and near-white shades, consistency, and whitespace.

In plain words
What is it for?
Use it to design or review colour palettes for websites, applications, and other user interfaces, including accessibility checks for text contrast.
Why use it?
It helps prevent noisy or hard-to-read colour choices and supports a clearer visual hierarchy.

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

color-principles 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.

What it actually says

Premium Color Principles

Seven principles for color that feels calm, premium, and accessible. Use them to review or design any digital interface — and reference them by number when giving feedback.

Triggers: color, palette, UI design, visual hierarchy, contrast, muted tones, accent color, design feedback, color theory.

The 7 principles

1. Reduce your palette

The fewer colors you use, the more each one matters.

  • 3 colors maximum
  • Neutral grays as the base
  • One accent color — for CTAs only

2. Use muted tones more often

If everything shouts, nothing stands out.

  • Avoid saturated colors for large areas
  • Muted tones read as premium and calm

3. Create intentional contrast

Contrast tells users where to look first.

  • Minimum 4.5:1 for text (WCAG AA)
  • Target 7:1+ for premium (WCAG AAA)

4. Use accent colors sparingly

Accent colors only work when they're rare.

  • One accent per view/screen
  • Reserve it for the primary action

5. Avoid pure black and pure white

Tiny shifts create different feelings.

  • Use #1a1a1a or #121212 instead of #000
  • Use #FAFAF7 or #F5F5F0 instead of #FFF

6. Keep color behavior consistent

Users shouldn't have to relearn your colors.

  • One action = one color, always

7. Let whitespace support color

Whitespace makes color intentional.

  • Don't crowd colors together

Feedback format

When reviewing a design, structure the response as:

  1. Assessment — which principles it follows or violates
  2. Analysis — specific feedback per principle
  3. Suggestions — concrete hex recommendations
  4. Priority — what to fix first

Pairs well with kika-design-system — these are the general review lens; that skill is one opinionated system built on them.

Changes

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.
