Consider the whole

A material is experienced alongside other surfaces, objects and everyday activity. A palette can be restrained while still giving each element a distinct role.

Make the detail useful

Connect the palette to the way a place is used. A surface near an entrance has a different everyday role from a quiet background behind a shelf. Discuss appearance alongside the relevant care information and the surfaces it will meet. Keep unresolved questions visible instead of describing an early visual study as an agreed specification.

Give each material a clear role

Begin by describing what an element is meant to contribute to the whole. It might provide a quiet background, distinguish a transition or make a frequently used detail easier to recognize. Compare a small number of adjacent combinations with those roles in mind. A restrained palette still needs differences in tone and texture to be considered carefully. The useful question is why a material belongs in that place, rather than whether it looks appealing on its own.

Record a choice that can be checked

Write down the exact reference behind a sample and distinguish a preferred direction from an agreed selection. Include the question that remains open, whether it concerns appearance beside another surface, care, availability or information that must come from a supplier. Keep a dated record of a change and the reason for it. This helps a conversation continue when a sample is replaced, without assuming that two visually similar finishes have the same technical properties or responsibilities.
