View samples in your own light
North-facing rooms often make colours feel cooler. Strong sun can wash pale colours out. Move a large sample around the room and look at it morning and evening.
Build a small palette
Choose the cabinet, worktop and floor together. Add wall colour and metal details after the main surfaces agree. Limiting the number of competing tones usually creates a calmer room.
Use dark colour with purpose
Deep green, blue-grey or charcoal can ground an island or tall unit bank. Balance it with lighter surfaces when the room has limited daylight.
