flowmanceMason Doe Design System
Mason Doe is a one-person portfolio on a charcoal page. It is quiet and grey almost everywhere, then very loud in two places: the full-width wordmark at the top and the photographs. The interface never uses colour. Text sits in a soft grey (#B7B7B7) rather than white, which makes the whole page feel matte, like printed matter on dark board.
Four signatures make it recognisable:
- The fat wordmark. MASON DOE set in Rammetto One, a heavy rounded display face, at about 184px, spanning edge to edge of the 2% page margin. In the live hero part of it is smeared by a WebGL blur (a Unicorn Studio scene), so the name looks partly out of focus.
- Two fonts with opposite jobs. Rammetto One is used only for names: the wordmark, project titles on the cards (Forma Digital, Studio Focus), job titles and company names in the experience list, award names and service pills. Everything functional (nav, meta, paragraphs, tags) is Inter 500–600 at 14–19px with slight negative tracking.
- Rounded portrait work cards. Two columns of tall photo cards with a 10px gap, broken by one full-width card. The project name sits bottom-left in Rammetto One and © Strategy, Concept sits bottom-right in Inter, both white over a soft blurred strip at the bottom of the image.
- The scroll-filled statement. The about paragraph (My passion for design began with a simple question…) is split into characters that start at 40% grey and fill to full #B7B7B7 as you scroll, so the sentence appears to be read out on the page.
Mason Doe is a dark-only design.

Do’s and don’ts
- Keep the page on canvas #111111 with text in ink-muted #B7B7B7; use white only on photos and section tags.
- Set names (projects, studios, awards, the wordmark) in Rammetto One and everything else in Inter 500–600.
- Open each about block with a dashed section-tag (7px radius, #B7B7B7 at 43% dashed border).
- Use underlined text links (label-link with a 1px line-soft track) for actions.
- Put work in rounded portrait cards (about 10px radius) in a 2-column grid with 10px gaps.
- Use 1px line (#B7B7B7 at 30%) rules under list rows.
- Add an accent colour, coloured buttons or drop shadows.
- Use Rammetto One for paragraphs, nav or buttons, or ask it for weights it does not have.
- Use ink-faint (40%) for anything except the unread part of the statement at 27px and above. It is a reveal state, not a text colour.
- Put a dark gradient on photos; use the 15px backdrop blur strip.
- Round cards beyond 14px, except the service pills at 30px.
- Add filled pill buttons; the template's only pills are service tags.

- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
