Paint an area
Colour is a great way to mark out areas in a space, as it can even change the mood from one area to another. Take this kitchen-diner for example, the crisp white kitchen is separated from the cosy eating area by a wall of teal. The inviting colour gives the area a welcoming feel, while the bright kitchen is a space for busy cooking.
Think about how you want to feel in a particular area, and choose shades to match - for example, a children’s play area could be surrounded by fun yellows and blues, while a snug seating zone would work well with calm, warm tones.
