ON.energy. High-voltage caution yellow on midnight steel.

ON.energy operates in a high-contrast industrial language: a single vivid yellow (#fff313) that functions as both full-bleed atmospheric section and functional accent against deep black surfaces, with no gradients or decorative effects in between. The type system uses Univers Next Pro at whisper-light weight 300 for all display and headline work — an anti-convention choice that creates authority through restraint rather than volume, paired with aggressively tight tracking (-0.04em at 36px+). Layout alternates between dramatic full-bleed color blocks (dark product photography, pure yellow statement sections, white content areas) rather than gentle cards-on-canvas, creating a rhythmic, almost industrial-signage quality. Radii stay small and utilitarian (6-9px), shadows are absent, and the component vocabulary is deliberately narrow: pill nav items, one yellow CTA, image cards, and a strong typographic hierarchy.
