Dev Tools · 1 screen · 12 sections · https://knock.app/

Light hero over a notifications workflow builder for product, marketing and transactional messaging.

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/knock.

Decoded design system

Knock's decoded design system: background #FFFFFF, text #1C2024, accent #FF6C52, link #041324, primary #FF6C52; type scale h1 56px / h2 18px / body 20px; 4px spacing base; 6px base radius. The single interactive/action color is #FF6C52 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F1F1F1`
border	`#DCDDDE`
text	`#1C2024`
text_muted	`#727477`
primary	`#FF6C52`
accent	`#FF6C52`
link	`#041324`
secondary	`#F45B58`
button_bg	`#FF6C52`
button_text	`#FAFAFA`

Using these colors

Action color #FF6C52 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #FF6C52 — one role, not several (the action color).
accent #FF6C52 — 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 #041324 — inline text links and link-styled controls.
secondary #F45B58 — 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.
