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.

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.
