About Behr Thermal Spring
Thermal Spring sits in the mid-range at LRV 37, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. Its green 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. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Thermal Spring is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Greens bridge indoors and out, so they suit living rooms, kitchens and sunrooms.
