A colour is not a HEX value once it is on a material. Gloss, texture, translucency, the substrate underneath and the way the surface ages all change what a colour looks like. This section describes how each major material produces, shows and loses colour, including recycled and reprocessed materials, whose colour is harder to control.
Optical properties are given as relative comparisons between materials, not measurements of a particular product. For what colours to pair with a material in a room, see Interiors → Materials.
