Best Rooms and Uses for Costa Rica Blue

How Lighting Changes Costa Rica Blue
At LRV 68, Costa Rica Blue is a light color that bounces daylight around a room without tipping into stark white. Its teal undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. It holds its undertone in most exposures, which is what makes light shades like this so forgiving room to room.
Most complaints about Costa Rica Blue are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
