The quality of a Blēo colour depends on the precise relationship between base and pigments, shaping depth, finish, and how the colour responds to light. This balance cannot be replicated through colour matching or codes alone, and substituting materials will alter the result. Each colour is developed through extensive research, testing, and refinement, with close attention to how it performs across surfaces and environments. To achieve the intended expression, colours must be produced through Blēo’s own system.
