Yellow & Sky Blue & Gray

Yes — yellow, sky blue and gray go together as Turku winter plaza — solar yellow riverside cathedral flash, pale sky blue Archipelago overcast air, and steel gray granite observer in one Finnish deck. First feel is turku-winter plaza — brighter than amber-sky-blue-gray Rauma winter plaza, built for tech and urban brands. Gray holds cool neutrality; sky blue is pale overcast; yellow activates so the mix refuses quiet concrete alone and owns wooden-town weight. Think a transit ad, a product UI with steel gray under pale sky-yellow CTA, or a city brand deck with a winter strip that keeps Turku gravity. Tech and urban brands lean on this triad for productive air-on-cool with Finnish harbor history. Let gray dominate — flood both chromas and it turns alarm costume. Turku winter: strong for city and tech, weak for soft spa.
