StoColor System

The StoColor System comprises of 800 colours for use in architecture — or can be matched to any colour using the Sto Spectrometer to meet any colour design preference.


The StoColor system is based on human visual perception. The six colour perception areas, consisting of the primary and secondary colours yellow, red, blue as well as orange, violet and green, form the starting basis of the StoColor System. Through the subdivision of these six colour areas into four further colour shade levels each, a 24-part colour wheel is created. This constitutes the basis of the StoColor System, which is incorporated throughout all Sto paints and Sto render finishes.
