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."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 CommonsFixed 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.
