What is brand-designer?

A color-palette generator creates coordinated brand colors from a starting color, logo, or design direction. It uses common color relationships such as complementary, triadic, and analogous colors.

Use it to customize website colors or create a new brand palette from hex codes, color names, descriptions, or a logo. It can also provide colors for a new site's visual style.

It removes guesswork when choosing colors that work together and keeps the palette balanced across a design.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00119	$0.01883
Opus 5	$0.00060	$0.00941
Sonnet 5	$0.00024	$0.00377
Haiku 4.5	$0.00012	$0.00188

Security

Grade A, and why

brand-designer 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.

Designing Brand Colors

Generate custom brand color palettes using color theory (complementary, triadic, analogous schemes).

Workflow

1. Check Prerequisites

Read site-specification.md for the design direction (base language, dials) and existing colors. During a new-site build (website-builder Workflow A style preview), the spec may not exist yet — take the base language from the chosen direction instead.

2. Get Colors

Accept: hex codes, color names, descriptions, or logo analysis (identify 1-3 dominant colors). When invoked from website-builder's style preview with no user colors, take the seed from the direction's palette strategy instead — pick a concrete base hue matching its stated hue family and temperature, and vary that pick per project.

3. Generate Palette

Compute hue rotation directly in OKLCH — no external API. OKLCH is Tailwind v4's native color space, and rotating hue there preserves perceived lightness, so schemes come out balanced (HSL rotation makes yellows glare and blues muddy).

Convert the base hex to OKLCH (oklch(L C H)).
Rotate H by the scheme angle, keeping L and C:
- Complementary: +180°
- Triadic: ±120°
- Analogous: ±30° (spread to ±60° for a wider family)
- Split-complementary: 180° ± 30°
Derive the neutral ramp from the dominant hue at very low chroma (C ≈ 0.005–0.02) so neutrals harmonize instead of reading as generic gray.
Adjust L per role — backgrounds near the extremes (L ≥ 0.97 light / L ≤ 0.22 dark), text at the opposite end, accents in the vivid middle (L 0.55–0.75, C 0.15–0.25).
Verify WCAG contrast (4.5:1 body text, 3:1 large text ≥18.66px or ≥14px bold) for every text/background pair; nudge L until it passes.
Check the stock Tailwind neutrals the site will actually use, not only the generated tokens. Contrast failures overwhelmingly come from off-palette utilities reached for during page authoring — text-slate-400 is 2.56:1 on white and fails at every size, and text-sky-600 is 4.10:1, which passes only as large text. Both look fine in a mockup and both ship as body copy. For each neutral and accent utility the design intends for text, compute its ratio and record the verdict in site-specification.md:

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.

brand-designer is a skill published in the GitHub repository teamniteo/hakuto (5 stars, last pushed 8d ago), licensed MIT. It adds 119 tokens to every session and 1,883 once invoked, about $0.0006 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.
