COLOUR-307 is an elevator cabin model that interprets color through smoother transitions and fluid surface relationships. The harmony between colors creates a calm yet contemporary architectural effect within the cabin. Colored panels, balanced lighting distribution and a clean ceiling layout provide a spacious, orderly and aesthetic interior experience. It is well suited for corporate buildings, commercial spaces and modern residential projects. COLOUR-307 stands out within KATRE LIFT’s colour series for projects seeking fluid color expression, architectural balance and contemporary aesthetics.
