As they are sensitive to a broad range of wavelengths covering the visible, they will react under any light, and so cannot distinguish between them. Colour photos (not digital photos) work by having different layers that are sensitive to different wavelengths, red green and blue, and so each reacts to different parts of the spectrum and the image can be reconstructed. Early colour photography however had to use a different technique, as such sentitive dyes were not available until 1907 and did not become common until the 20s and 30s.
