Cartesia
A near-monochrome, research-lab-flavored AI voice interface anchored on white canvas with deep-forest-green brand accents and a recurring dark charcoal surface mode. The system reads as quiet, technical, and confident — sober neutral grays carrying the structure, a single dark-green primary accent doing the brand work, and a small organic palette of soft greens, warm beige, and terracotta appearing as supporting tints. Color is the only firmly-measured layer; type, spacing, and radius are read from screenshot ground-truth and flagged as derived.
