Rum

Rum is the gray you notice on a dusty metal shelf, a little heavier and more grounded than the cleaner, airier Excalibur. It sits mid-light, but it doesn't float. The tone leans a touch toward a muted brown-leaning calm, which keeps it from taking on the slightly bluish restraint of Mamba.

I use Rum as the underlayer for dense admin and product UI when the design needs structure without that cool neutrality pressing in. Think insurance portals, HR systems, and internal dashboards where tables, tabs, and form rows all sit close together. Compared to Paris Paving, it's less "paved" and concrete settled, more like a gray with a soft, neutral weight that reads consistent across lots of small UI states.

Pair it with foregrounds that have enough ink weight. With thin type it can start to feel muted, so I treat it as the background that asks for clear contrast, not the one you disappear into.
