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).
## Color
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.

03 — Typography
## Primary Typeface
**Lateral** is our primary typeface. Use it for headlines, product UI, and anything that needs presence. Give it room when setting editorially.
## 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.
