Blackalgo vs Convex

Blackalgo runs a dark-canvas system while Convex chose light, and they pair different display families (TWKLausanne vs gtAmerica). Beyond surface, motion divides them — Blackalgo is expressive, Convex is subtle.

Palette & spacing overlap

Their palettes share 5% of swatches at the dominant tier — a quiet signal both teams drew from the same neutral library before applying brand accents. Their spacing scales overlap by 83% (2, 4, 6, 8, 10 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict

Pick a side. Mixing Blackalgo's dark-first canvas with Convex's subtle motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Blackalgo's spacing, Convex's shadow).
