Mixtures of water ice and organics seem to pervade surfaces in the outer Solar System, from the rings of Saturn to the Kuiper Belt Objects. The early Earth was bombarded by the leftover planetesimals from the formation of the planets, and these must have been rich in both ice and carbon to provide the building blocks of life. Scattered light from debris disks is remarkably similar in albedo total scattering efficiency and color red to the objects in the outer solar system. Thus, we have a hint that the same photochemical processes that happened close to home also happen around other stars. We propose to study the color of two debris disks in some detail. Scattering of light is the only window available to us to see the composition of debris disks in a spatially resolved manner and to assess their potential for containing planets like ours.
