Warm, without any doubt. Biscuit sits at the yellow-cream end of the white spectrum — it's not a gray-white or a blue-white. Under warm artificial lighting, it can read quite amber and golden. Under cool daylight or overcast conditions, it settles back to a soft cream. It pairs naturally with timber, linen, stone, and other warm natural materials. If you're working with a cooler palette — lots of gray, white, or blue — Biscuit may read as slightly yellow in contrast. In those cases, Natural or Snow might be a closer match to the room's mood.
