Missive — design system & UI screens

Communication · 1 screen · 10 sections · https://missiveapp.com/

Light editorial hero over a shared-inbox product UI with assignments and internal chat.

This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/website/missive.

Decoded design system

Missive's decoded design system: background #FFFFFF, text #34363A, accent #2266ED, link #3898EC, primary #2266ED; type scale h1 56px / h2 30px / body 18px; 8px spacing base; 8px base radius. The single interactive/action color is #2266ED — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F2F2F3`
border	`#E0E0E1`
text	`#34363A`
text_muted	`#818284`
primary	`#2266ED`
accent	`#2266ED`
link	`#3898EC`
secondary	`#0082F3`
button_bg	`#2266ED`
button_text	`#FFFFFF`

Using these colors

Action color #2266ED — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #2266ED — one role, not several (the action color).
accent #2266ED — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
link #3898EC — inline text links and link-styled controls.
secondary #0082F3 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
