flowmanceTulsa Design System
Tulsa is a dark, calm marketing-firm site. It feels like a product studio lit by one soft spotlight: a warm charcoal page, pale sage-grey headlines in Inter Tight 600, square slate-teal cards, and colour held back to a single green glint inside glass 3D renders. The live brand mark is spelled Tūlsa with a macron.
Four signatures make it recognisable:
- Dimmed second halves. The hero lines, leads and statements start in ink #D3E0E0 and ends at 60% opacity: The virtual / marketing firm., Enabling the progress of newly established companies.
- Slate-teal square blocks. Service cards, logo tiles, testimonials and the contact panel are all #4B5959 rectangles with 0px corners on the #2A2C29 canvas.
- Spotlit hero. A full-viewport photo backdrop (hero.png, cover) gives a grey-green light falling from the top, with a glass-and-green 3D cube on the right.
- Frosted buttons on photos. View full project and Contact us are 5px-radius buttons in white at 40% with a white inner wash, sitting on images and panels.

Do’s and don’ts
- Split hero lines, leads and statements into two tones: ink #D3E0E0 then ink at 60%, same size and weight 600.
- Keep blocks square: surface-1 #4B5959 cards, tiles and panels with 0px corners on canvas #2A2C29.
- Set paragraphs at 18px weight 500 in white at 70%.
- Use the gradient pill (#435152 → #4B5959 → #96A59E) for the one main action, and the frosted 5px glass button over photos.
- Keep 100px vertical section padding and the 1200px container.
- Let green appear only inside glass 3D renders.
- Use ink-subtle (60%) for text under 17px or on surface-1 cards for anything but names and companies; it drops below 4.5:1 there.
- Add bright accents, pure white headlines or pure black backgrounds.
- Round cards, images or inputs.
- Add drop shadows or blur; the only shadow is the inset white wash on frosted buttons.
- Use uppercase except for footer tags and the cursor circle.
- Speed scroll reveals below 1000ms or use bounce easing.

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/tulsa.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
