A single space combining two or more functions — commonly kitchen, dining and living — where colour choices need to work across several uses and light conditions at once.

An open-plan room like this one has to work as both a dining space and a living space under one shared light source — the pale, neutral wall shown here is a common low-risk choice precisely because it reads consistently across a room used for more than one purpose.
This combined dining/living space is lit by one large window at an angle to the room, so brightness and colour genuinely vary across the frame — the palette was reviewed to represent both the wall and the warm floor together.Photo: “HK SYP Sai Ying Pun Hing Hon Road Hilary Court Bonham Road 38B dining room and living room” by YSSKACH WFAMOACSH TUNGA, CC BY-SA 4.0, via Wikimedia Commons.
Fixed materials: Kitchen units at one end of the space usually constrain colour choice for the whole room more than a standalone kitchen would, since the scheme needs to work from both the kitchen and the living side.
Directions that tend to work: One consistent neutral used throughout, with a secondary tone or single accent wall to define a zone, is a common and low-risk approach for a large, multi-orientation space.
Colours that can be difficult: A colour chosen from how it looks at only one end of the room can look noticeably different — cooler, warmer, darker — at the other end.

Soft greige open-plan scheme
Cohesive and calm across a large, multi-use space.
Low contrast between primary and secondary wall by design, so the space reads as one room rather than several competing ones.
An open-plan room commonly has different orientations and light levels in different zones — the same wall colour can look noticeably different at each end of the room; test a sample in every zone.
