flowmanceKai's Design System
Kai's is a personal portfolio printed in two colours, like a risograph poster: a warm stone page (#E8E6E0) and one cobalt blue ink (#1925AA) for every word on the page and the logo. The hero is the owner's name, KAI FOX, in condensed Anton so large that the two words fill the width, with a tilted black-and-white portrait wedged between them. Everything else is small uppercase Inter set in the same blue.
Four signatures make it recognisable:
- One blue, no greys. Text is never black or grey; it is #1925AA at full strength on a warm off-white. The menu and footer invert it: stone text on a blue panel.
- The giant Anton name. KAI FOX at 33vw (475px at 1440) with line height 0.85. Section titles use the same face at 22vw (WORK). A tilted photo (rotated about 8°, 12px radius) overlaps the name.
- All-caps Inter paragraphs. Body copy, hero lines and service lists are Inter 16px, weight 600, uppercase, −0.5px tracking. The page reads like a typeset label, not an essay.
- Hand-drawn notes. Small italic annotations in brackets, (contact me) and (hover us), with thin curved arrows drawn in blue, point at the email and the service list. A scribbled signature closes the about text.
Kai's is a light design with blue (inverse) menu and footer panels.

Do’s and don’ts
- Print every word in ink #1925AA on canvas #E8E6E0; invert to #E8E6E0 on #1925AA for the menu and footer.
- Set names and titles in Anton uppercase, line height 0.85 at display sizes, filling the width.
- Set paragraphs in Inter 16px, weight 600, uppercase, −0.5px tracking.
- Give photos a 10px radius and put the project name and © YY in a row beneath.
- Add at most one lowercase italic bracket note with a drawn arrow per screen.
- Keep the 110px blurred strip at the top so content softens under the nav.
- Use black, grey or a lighter blue for text. ink-muted is the same blue.
- Add filled buttons, borders or drop shadows.
- Write sentences in Anton or titles in Inter.
- Load Caveat expecting handwriting unless you also load it; as published the notes are a serif italic.
- Add a third interface colour; let the photos bring orange, green or red.
- Shrink the hero name to fit a layout; it should run edge to edge at 33vw.

What it is
The whole design system in one markdown file, written for AI: every color, type style, spacing value, component and motion rule, plus do's, don'ts and a ready prompt.
Best for
Claude, ChatGPT, Gemini, Cursor and v0, or any other AI tool that builds pages or code.
How to use it
- Put
DESIGN.mdin your project and mention it in your request, or save it as.cursor/rules/kais.mdc - For the rule file, start it with a front-matter block that sets
alwaysApply: true, so every chat uses it - Ask: “Build a pricing page using DESIGN.md.” Cursor follows the colors, fonts, spacing and rules
- Put
DESIGN.mdin the project root - Add one line to
CLAUDE.md: “Follow DESIGN.md for all UI.” - Ask for any page or component; Claude reads the file first
- Attach
DESIGN.mdto the chat (or paste it in) - Ask: “Build a landing page in this design system.”
- Keep the file in the chat or project knowledge, so follow-up pages stay on style
What it is
Every token as data, in the W3C Design Tokens format: colors with their roles, type styles, radius, spacing, and component tokens that point at them.
Best for
Figma (Tokens Studio), Style Dictionary and other design-token tools, and build scripts.
How to use it
- In Figma, open Tokens Studio, choose Import, and pick
tokens.json - Or point Style Dictionary’s
sourceat it to generate tokens for any platform - In code, import it like any JSON file
What it is
A Tailwind CSS v4 theme: every color, font, type style, radius and spacing value becomes a Tailwind utility, like bg-canvas, text-headline-lg or rounded-md.
Best for
Tailwind v4 projects, and AI builders that write Tailwind (v0, Lovable, Bolt).
How to use it
- Save
theme.cssnext to your main CSS file - Import it after Tailwind:
@import "tailwindcss"; @import "./theme.css"; - Use the classes:
bg-canvas text-ink rounded-md p-lg
What it is
The same tokens as plain CSS variables on :root. Component values point at the color variables, so changing one color updates everything that uses it.
Best for
Any website: plain CSS, Webflow custom code, Framer, WordPress.
How to use it
- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
color: var(--color-ink) - Change a token once and every place that uses it follows
