flowmanceULF Design System
ULF looks like a fashion magazine cover for an agency. A white page carries huge Melodrama headlines (a high-contrast display serif with hairline strokes) at 120px, centred, with a small black four-petal mark sitting inside the headline like a word. Everything around it is quiet Satoshi: grey uppercase eyebrows, grey uppercase paragraphs, light-grey buttons. Halfway down, the whole page turns black for the work and team sections.
Four signatures make it recognisable:
- Melodrama at 120px. Hero and big section words (Accelerate the growth of your brands., Improve, Our Work) are Melodrama 500 at 120px with line height 1.0, centred. The nav uses the same face at 19px Bold.
- The inline petal mark. A black four-petal shape (60px image in an 80px inline slot) replaces a word inside the headline, before brands. and after Testimonials.
- Grey caps under serif. Small type is Satoshi in #666666: 13px Bold eyebrows with 2px tracking (MEET ULF TEMPLATE, WHAT WE DO) and uppercase paragraphs at 14–15px.
- The white-to-black flip. The page starts white with black type; when the work section scrolls in, the background, nav and text switch to black and white.

Do’s and don’ts
- Set headlines in Melodrama 500 at 120px, line height 1.0, centred on the hero.
- Put a 13px Satoshi Bold eyebrow with 2px tracking in #666666 above section titles.
- Keep body copy #666666 Satoshi 500 at 18px/24px on #FFFFFF.
- Use the #EEEEEE button with a 6px radius that turns #000000 with white text on hover.
- Switch whole sections to #000000 with white type for the work and team area.
- Round photos at 30px and keep them full colour.
- Set body copy or buttons in Melodrama; it is for names and headlines only.
- Use black for paragraphs or grey for headlines.
- Add the unused #B5D99C green or any other accent.
- Add shadows, gradients or tinted overlays.
- Use pill buttons; buttons stay at 6px.
- Put the 57% white footer link colour on anything smaller than 16px.
- Use price-ink #8A8A8A for anything but 24px price tags; on white it is only 3.45:1.

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/ulf.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

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:
