"Core" has been retired. The wordmark stands alone. Below are three candidate marks, each drawn on the same 64-grid, single color, tested from 16px favicon through hero scale.
"From parts, a company."
Five discrete modules resolve into an unmistakable H. Reads as a system being built — the literal act HEXIUM performs. Highest memorability of the three; the eye reconstructs the letterform on every viewing.
"The letter, engineered."
Two pillars, a crossbar that rises. Feels closest to Stripe/Linear: quiet, precise, ownable. The tilted bridge encodes growth without being decorative. Best pure typographic mark.
"From an idea, a company emerges."
A single seed contained within an expanding squircle. The most conceptual mark — literal metaphor for what HEXIUM does. Highest trust register; closest to OpenAI/Notion in restraint.
The canonical mark below remains active until a direction is selected. Once chosen, it replaces HexiumMark at every entry point — header, sidebar, favicon, app icon, hero.
The HEXIUM mark is two identical forms, offset and joined into a single silhouette. It is the operating system that runs businesses, drawn as a shape: many things working as one.
The mark is always one color. It inherits from currentColor, so it adapts to any surface without overrides. Two states only: solid (default) and outline (for stamping over photography or video).
Typography: system-ui semibold, tracked +0.18em. The mark height matches the cap-height of the wordmark. Gap between mark and wordmark is fixed at one quarter of the mark height — never adjust it manually.
Clear space: a margin equal to one third of the mark height on every side. Never crowd the mark with text, rules, or other logos inside this zone.
Minimum size: 16px on screen, 4mm in print. Below that the offset between the two forms collapses and the silhouette stops reading.
Show the mark for five seconds. Walk away. Sketch it tomorrow. The HEXIUM mark passes because it is two of the same shape, offset. Anyone can draw it from memory — that is the design.
