In this work, we propose a CNN-based approach to estimate the spectral reflectance of a surface and the spectral power distribution of the light from a single RGB image of a V-shaped surface.

Light interreflections occurring in a concave object generate a color gradient which is characteristic of the object's spectral reflectance.
