flowmanceOptune Design System
Optune is a dark, glowing marketing-agency site. Everything sits on pure black, lit by a beam of electric blue light that falls from the top of the screen across a faint geometric line pattern. The type is a clean sans (Geist) with single words swapped into Playfair Display italic, and nearly all body text is uppercase. Cards are frosted glass at 5% white, with a few bright white cards for contrast, and every action is a glowing blue gradient pill.
Four signatures make it recognisable:
- Sans plus serif italic. Headlines mix Geist 500 with one or two words in Playfair Display italic: Building the next era of marketing, Proven results, every time, Integrate to your favorite workplaces.
- Fading text. Headlines and quotes fade from solid to 40% along the line with a text gradient (-90deg, white 40% → white), so the last words look lighter (the next, save, who we are). On white cards the same fade runs in black.
- The glowing pill. Buttons are 50px-radius pills filled with a 20° gradient from #110FDF to #7468FC, uppercase 14px labels, and a soft blue glow below (0 7px 80px -12px #110FDF).
- Glass everywhere. Nav, tags, metric cards, the awards table and process cards are white at 5% with a 40px (or 15px) backdrop blur and a 6.4px radius. The nav is a floating 100px-radius capsule that widens from about 680px to the full 1260px container once you scroll.
Optune is a dark-only design with white contrast cards.

Do’s and don’ts
- Keep the page pure black #000000 with the fixed line pattern and a blue light beam behind it.
- Pair Geist 500 headlines with one Playfair Display italic phrase at the same size, and fade the tail to 40%.
- Set leads, body, labels and buttons in uppercase Geist 400–500.
- Use glass cards (white 5%, 40px blur, 6.4px radius) and a few white cards for contrast.
- Use the gradient pill (#110FDF → #7468FC, 50px radius, 47px tall) with its blue glow for every action.
- Start tags with a thin + icon.
- Use flat solid blue panels or a second accent; the green and red are only tiny status tints.
- Round cards beyond 6.4px; only buttons, tags and the nav are pills.
- Use ink-faint (white 40%) for readable body text; keep it for meta and the faded ends of large headlines.
- Set the Playfair accent in roman or bold; it is italic, weight 400.
- Add drop shadows to cards; the only shadow is the button glow.
- Use the unused #9ADBFF button colour or #1DD35A neon green.
