Brand guidelines · v1.0

The Gatum mark.

A confident neo-grotesque wordmark with a single electric-blue period — our signal that a message just arrived. Use it boldly. Don't over-decorate it.

Give it room to breathe

Reserve a minimum padding of 1x on all sides — where x equals the diameter of the blue period. Nothing else lives inside this frame.

03 · Sizing

Minimum sizes

The wordmark must always be legible at small sizes. Below 80 px wide (digital) or 20 mm (print), use the favicon mark instead.
