暖色と寒色の分離：感情ツールとしてのホワイトバランス

Create an interior visualisation built on a deliberate split between cool daylight and warm artificial light. Show a room with a large window admitting cool blue-tinted daylight from one side, and warm 2700K lamps lit within the room, so the two light sources meet and the boundary between them is visible on the walls and floor. Detail the surfaces where they overlap as taking a mixed neutral tone, with the pure cool and pure warm zones at either extreme. Show the shadows cast by the warm lamps as slightly blue, filled by the daylight, and the shadows cast by the daylight as slightly amber, filled by the lamps — the reciprocal relationship that makes such images convincing. Detail the white balance as set for neither, sitting between the two so both casts remain visible rather than one being neutralised. Show a figure or an object standing in the transition zone lit from both sides in different colours. Keep the palette to cool blue-grey and warm amber with little else. Photorealistic, split lighting, blue and amber, eye-level view.
