What a sample room actually proves
It confirms colour under the real site lighting, sheen level against the client's expectation, coverage of any branded colour over the existing substrate, and how a particular product performs on that unit's actual wall condition — none of which a colour chart or a small sample card can fully demonstrate.
- Colour checked under the unit's actual lighting, not a showroom light
- Coverage confirmed over the specific existing substrate
- Sheen and texture agreed by physical inspection, not description
