Color Temperature
Describe a light's warm or cool character in relation to white balance and the other sources in the scene.
Prompt
Use Color Temperature contrast: switch on the existing hanging lamp as a warm 2800K source, illuminating the top-left planes of the original head and shoulders and the nearby wall. Keep daylight entering the existing left window cool around 6500K, visible on the lower side planes and desk, with a middle white balance that keeps both source colors readable. Preserve original red, cream and teal material colors beneath the illumination. No arbitrary split-color face, new fixture or full-image color filter.

Effect comparison
In the baseline image, Ruk and the studio have mostly neutral daytime colors. The color-temperature version uses a warm pendant light on the figure's upper surfaces and nearby walls, while cool light from the left window reaches the table and floor. Warm and cool sources meet within the same space, giving the figure and background more distinct layers of color.
