Why can a warm shadow occur under cool light?

Answer and explanation

Correct answer: Because of reflected light from warm surfaces

The governing concept is reflected-light colour. A shadow is not an independent substance; it is an area receiving less direct light, while reflected illumination may still reach it. If nearby warm surfaces reflect reddish or yellowish light into that area, the shadow can appear warm even though the main light is cool. The shadow does not heat itself, black paint is not the cause, and blue light does not simply disappear.
