Design language comparison

Comet vs Runway

Both Comet and Runway commit to a dark-canvas approach, and they pair different display families (system-ui vs abcNormal). Beyond surface, motion levels are both expressive.

Palette & spacing overlap

Palette overlap is zero — Comet and Runway live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 25% (8, 16, 32 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict

If you are building an interface that needs to reference both, Comet's restraint reads as the safer default and Runway's rhythm provides the accent moments — pair them at section-level, not at component-level.
