flowmanceMavon Design System
Mavon is a quiet, warm-grey studio site. The whole page sits on one putty grey (#C1C0B7) with charcoal (#3F3B38) text, and it feels like a printed brochure on uncoated stock: big semibold Inter Tight, very few elements, and lots of empty grey. Colour arrives only through the project images (a red billboard, a red laptop screen) and through floating chrome 3D starbursts in the hero.
Four signatures make it recognisable:
- One charcoal pill. The only button is a dark #3F3B38 pill (30px radius) with putty-grey text: Let's Work, About Us, Send Message, and the fixed Menu pill top-right. On hover it turns white with charcoal text.
- Words that reveal as you scroll. Lead paragraphs are 29px semibold, split into words, and each word goes from faint to full charcoal as it scrolls through the viewport, so a half-read paragraph shows a solid start and a grey tail.
- Viewport-wide rolling text. Lines like …world class expe… run at 12vw (173px at 1440) across the screen over a large #B2B2A9 circle, and project names (Tuscon Doe) roll at 5vw over the work images.
- The red dot label. Section labels are 18px semibold with a small #CB564B dot before them: • Featured Work, • Top Client. That dot is the only accent on the page.
Mavon is light-only. There is no navigation bar: just a 60px logo fixed top-left and the Menu pill fixed top-right.

Do’s and don’ts
- Keep the whole page on putty #C1C0B7, with #B2B2A9 for the news, contact and footer block, and all text in charcoal #3F3B38.
- Use the charcoal pill (#3F3B38, #C1C0B7 text, 30px radius, padding 17px 30px) for every action; on hover turn it white with charcoal text.
- Put an 8px #CB564B dot before every section label.
- Set leads at 29px weight 600 and reveal them word by word on scroll.
- Use vw sizes for the giant lines (12vw, 10vw, 5vw) so they span the screen.
- Keep photos square-cornered and full-colour.
- Add a second accent, a gradient, or white cards; white is only the hover state.
- Use the red for text or large fills.
- Add shadows or borders to images or cards.
- Use weights above 600 or negative tracking; Inter Tight is already tight.
- Add a top navigation bar; the logo and the Menu pill float on their own.
- Use pure black or the unused #2E5CFF blue.

Pick a file to see what it’s for and where it goes.
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/mavon.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
