Kami is a constraint-based design system that gives AI-generated documents a consistent editorial language through one accent color, serif-led hierarchy, and a warm parchment canvas, and can also guide image renderers such as Claude Design or GPT Canvas.

What can Kami produce?

Kami includes eight document templates, a multilingual landing-page system, and 18 inline SVG diagram types. Documents export to PDF or PNG, and slides also have an editable PPTX path.

Can Kami match my brand?

Yes, share your brand colors, fonts, and layout preferences or provide a brand profile, and your brief will override Kami's defaults.

What languages does Kami support?

Kami supports English, Chinese, Japanese, and Korean with Charter, TsangerJinKai02, YuMincho, and Source Han Serif K respectively, plus per-language tuning for spacing, line height, and type size, while Japanese and Korean remain best-effort CJK paths with visual QA before delivery.

Design Principles

Warm parchment canvas, ink blue as the sole accent, serif carries hierarchy, while hard shadows and flashy palettes recede. This system is built for printed matter: stable, clear, and composed. Parchment is the default; an opt-in white-paper variant prints any document on a white background while keeping the warmth in cards and tables.

1
Page background is parchment #f5f4ed, never pure white
2
Accent color is ink blue #1B365D only; no second chromatic hue
3
All grays are warm, yellow-brown undertone; no cool blue-grays
4
One serif family carries headlines and body; add a distinct sans only for real UI chrome
5
Serif body at 400, headings at 500. Avoid synthetic bold
6
Three line-height bands: tight titles 1.1-1.3 / dense 1.4-1.45 / reading 1.5-1.55
7
Tag backgrounds must be solid hex; no rgba, WeasyPrint double-rectangle bug
8
Keep surfaces flat by default; reserve a whisper shadow for real floating elements

03 · Color

Warm Restraint

One accent + warm neutrals + zero cool colors. Ink blue covers no more than 5% of any page. Beyond that is clutter, not restraint.

Quick Reference

When in doubt about what to use, consult this table. If it's not here, go back to first principles.

Task	How
Large headline	serif `500`, size by hierarchy, line-height `1.10-1.30`
Reading body	serif `400`, `9.5-10 pt`, line-height `1.55`
Emphasize a number	`color: var(--brand)`, not bold
Separate two sections	Whitespace first; one `0.5pt` neutral full-width hairline only when the boundary must be explicit
Quote someone	Olive text + italic or indentation; no side rule
Show code	Ivory bg + `4pt` radius + mono font, no border
Primary vs secondary	Primary: brand fill + ivory text; Secondary: warm-sand + charcoal
Mark a special card	Use a stronger label or one quiet fill; do not add an accent edge
Begin a section	Serif `500` · `15pt` · size-led hierarchy, no decoration needed
Document cover	Single page, Display size + right-aligned author/date + generous whitespace
Show key figures	Baseline row, transparent, no container + serif number, ink blue + sans label

09 · Anti-Patterns

What to Avoid

Exceptions are allowed, but the reason should be explicit.

Page canvas

NeverPure white #ffffff or cool gray #f3f4f6 as page background. It makes the page feel brittle and weakens the warm parchment character.

InsteadAlways #f5f4ed parchment, with @page background set to the same color to avoid white edges when printing.

Tag tints

Neverrgba(27,54,93,0.18) for tags. WeasyPrint renders padding and glyph areas at different opacity, creating double rectangles.

InsteadUse the registered default tag token #E4ECF5. The rendering stays clean and the color remains stable.

Synthetic bold

NeverHeadlines at font-weight: 600 or heavier synthetic bold. It blurs strokes and degrades typographic quality.

InsteadBody 400, headings 500 (real W05). For more presence, use size, spacing, or ink-blue text, never synthetic bold.

Shadows

NeverHard drop shadow 0 2px 8px rgba(0,0,0,0.3). Visually heavy and likely to print as dark blobs.

InsteadKeep the surface flat. Use whitespace, one quiet fill, or a neutral hairline; reserve a whisper shadow for real floating UI or screenshots.

Design Origins

I like investing in US equities and ask Claude to write research reports all the time. Every output landed in the same default-doc look: gray, flat, a different layout each session. The structure was hard to scan, the formatting felt dated, and nothing about the page made me want to keep reading. So I started fixing the typography, the palette, the spacing, one rule at a time, until the report became a page I actually enjoyed.

Later I needed to present "The Agent You Don't Know: Principles, Architecture and Engineering Practice." I already had the document and didn't want to build slides from scratch, so I used Claude Design to lay it out in my own style, tweaked it round after round, and eventually got it to a place I was happy with. That process added inline SVG charts, a unified warm palette, and a tighter editorial rhythm. It kept growing until it covered every document I regularly ship, so I kept abstracting the process, and it became kami: one quiet design system I can hand to any agent and trust the output.
