Black and white carry the brand. Maroon and Gold are heritage accents — use them only for emphasis and legacy moments, never as the base palette.

01 — Logo

Primary Logo

The Sei primary lock-up consists of two elements: the symbol and the wordmark. This lock-up is the main representation of the brand and should be used consistently as a combined unit.

Symbol

The symbol is the standalone Sei mark. Use it on its own only when the wordmark is already established elsewhere on the surface (favicons, app icons, watermarks).

Token

The token mark appears in Maroon. Black and white are fallbacks for constrained environments.

04 — Usage

Clearspace

To maintain the logo’s clarity and prominence, follow the clearspace guidelines. A certain amount of space is required around the lockup to prevent surrounding artwork, imagery, or the edge of a page from crowding it.

• Use only approved colors. Black, white, Maroon 100, or Gold 100 — nothing else.
• Keep proportions locked. Symbol and wordmark ship as one unit. Don’t rescale their relationship.
• Respect clearspace and minimum size. X on all sides, 25 px tall minimum.

Cobranding

Our lockup for brand partnerships is dictated by the clearspace rule, which should also be applied to the partner brand. Ensure both lockups are the same height.
