Monzo banks in its own voice: custom Monzo Sans Display at 49px/800 speaks with high-street warmth, body text runs a generous 20px for genuine readability, and 500px-radius pills in deep navy anchor the hot-coral card photography. Bright product shots and plain-English copy make regulated finance feel like a friendly app store listing — consumer fintech at its most legible.

Tokens

Monzo's decoded design system: background #FFFFFF, text #091723, accent #FF4F64, link #091723, primary #112231; type scale h1 49px / h2 40px / body 20px; 4px spacing base; 16px base radius. The single interactive/action color is #091723 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F1F1`
border	`#DADCDE`
text	`#091723`
text_muted	`#666F76`
primary	`#112231`
accent	`#FF4F64`
link	`#091723`
secondary	`#0000EE`
button_bg	`#091723`
button_text	`#FFFFFF`

Using these colors

Action color #091723 — the single interactive color; only on things you click or must notice, never large fills.
link, button_bg are all #091723 — one role, not several (the action color).
accent #FF4F64 — accent for emphasis — keep it rare on the page.
primary #112231 — a brand color — but the call-to-action uses #091723, not this.
secondary #0000EE — 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.
