カラーグレーディング：局所的な調整ではなく全体的なロジック

Take the supplied architectural render and apply a coherent cinematic colour grade across the whole image. Lift the blacks so the darkest point in the frame is a soft dark grey rather than pure black, giving the image a filmic base. Push the shadows toward a cool teal and the highlights toward a warm amber, with the mid-tones left close to neutral, so the image has colour separation between light and shade rather than a uniform cast. Apply a gentle S-curve to the contrast, opening the mid-tones while holding both ends. Reduce the overall saturation slightly, then selectively restore it in one or two elements only — a figure's coat, a lit window, a single plant — so the eye has somewhere to land. Add a subtle vignette darkening the corners by a small amount. Finish with a fine even grain across the entire frame, including the sky, at a strength that is felt rather than seen. Keep every adjustment global and consistent — no local dodging that would break the light's logic. Photorealistic, graded, teal and amber, filmic.
