flowmanceCloudy X Design System
Cloudy X is a light, friendly fintech and startup site. It feels airy and optimistic: a white page, near-black Inter at weight 600, and a soft mint (#E1F6EF) that shows up as the main buttons, tags and icon circles, with sage-green (#529774) text on every mint fill. Product UI fragments (a balance card, a phone app) float over cut-out people, which gives the page an app-store, consumer-finance tone.
Four signatures make it recognisable:
- Mint pill + sage text. Main buttons, section tags and active tabs are mint pills with sage text and no contrasting border; buttons add a small →. There is no dark filled button anywhere.
- Tag, then title. Most sections open with a small mint tag (Get Started, Testimonials, Core Features, Why choose us) and a headline-md title under it, usually centred; the testimonials tag and title sit left-aligned.
- Cut-out on a circle. The hero puts a background-free portrait on a large mint circle, with a floating white payment card (Balance $5,756, light shadow) overlapping the bottom edge and a small mint icon circle at the top left.
- Highlighted word. The hero title marks one word (smarter) in sage on a slightly tilted mint block, like a highlighter stroke.
The live site brands itself ClodyX / Clody X. Cloudy X is light-only.

Do’s and don’ts
- Use mint #E1F6EF pills with sage #529774 text and a small → for main actions; secondary actions use the sage line link or outline pill.
- Open most sections with a mint tag (usually centred) and a 39px headline-md title in #131B14.
- Write two-tone leads: the first clause in #131B14, the rest at 70%.
- Use white cards with a 1px #E9E9E9 border, 12–15px radius and the 0 2px 12px #0F0F0F0F shadow.
- Place cut-out people on mint circles with floating white UI cards overlapping them.
- Keep the green gradient (#53CC8E to #529774) for one feature band only.
- Use sage-on-mint below 14px or for paragraphs; it is only about 3.1:1. Keep button and tag text 14–17px semibold.
- Add a dark or black filled button; the system has none.
- Use the unused CSS colours #3347FF or #C1F6F6.
- Use heavy shadows or hard offsets; the one shadow is 6% black.
- Use uppercase tags or letter-spaced labels.
- Animate longer than 1000ms or use bounce easing.

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/cloudy.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

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

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.

How to use it
- Save
theme.cssnext to your main CSS file - Import it after Tailwind:
@import "tailwindcss"; @import "./theme.css"; - Use the classes:

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:
