Brand

The UNDO logo, colour palette, typography and the usage and wording rules for anyone who writes about or displays the brand.

Logo

The UNDO whorl

Use it on the paper background, with clear space of at least a quarter of its width on every side.

The UNDO logo is a round whorl of soft blue stems. It turns back on itself, like an action being undone.

Use the file from the download link above. Do not redraw it, trace it or rebuild it from a screenshot.

Colour	Hex	Use
Warm grey	`#DDD6D1`	Page background
Card surface	`#EEE9E5`	Cards and panels
Ink	`#14122B`	Body text
Muted	`#5E5A66`	Secondary text
Near-black navy	`#0A0620`	Deepest tone in the logo and illustrations
Ultramarine	`#0B1F8F`	Deep blue in the logo and diagrams
Electric blue	`#0A5BFF`	Primary accent: links, buttons, focus
Cyan-teal	`#35B8C9`	Secondary accent in diagrams
Pale mint	`#BFE8D2`	Soft highlights, positive states
Glowing cream	`#FFF3B0`	Glow and emphasis, used sparingly

Electric blue is the primary accent. The background is warm grey, never pure white.

Typeface	Use
Instrument Sans	Headings and UI
Geist Mono	Numbers, addresses and amounts

Set every amount, address, percentage and parameter in Geist Mono. Write numbers exactly: 2,500 USDC, 0.5%, 48h.

Keep clear space around the logo. Nothing should touch or crowd it.
Do not recolour it.
Do not place it on pure white or on dark backgrounds. It is drawn for the warm grey background.
Do not pair it with third-party logos. UNDO is an independent project, and a lock-up with another logo implies a relationship that does not exist.
Do not rotate it faster than the site does. The site gives it one slow turn.
Do not stretch, crop, outline or add effects to it.

These rules apply to anyone describing UNDO: press, integrators, community members and us.

Topic	Rule
Name	UNDO, in capitals. The token is $UNDO.
Tagline	"Payments are final. Mistakes shouldn't be."
Secondary line	"Ctrl+Z for USDC payments."
Core line	"The money moves, the guarantee stays." Quote it exactly or not at all.
Status	"In development. Simulation only." Do not describe the protocol as live.
What it is	Buyer protection for USDC payments on Arc.
Words to use	Protection, bond, refund.
Words to avoid	Any term borrowed from regulated cover products, and any claim that an outcome is certain or without risk.
Guarantee Pool	A proper noun for a planned phase 2 component. Do not use the word in any other sense.
Other companies	"Built on Arc" as plain text only. Do not state or imply a partnership with, or an endorsement by, any company.
Token	Not launched. No price talk, no return talk. The contract address is announced only on X.

Keep the tone plain. Short sentences, exact numbers, no hype.
