The color of an extrasolar planet is an important property because, for the case of direct detection, color is likely to be the first post-detection quantity to be measured. We show here that color carries considerable information on planetary properties. The next most likely measurable quantity is a low resolution spectrum, and we show what additional information this carries. Several other aspects of direct detection are discussed, including the respective benefits of visible and infrared detection, techniques of visible coronagraphic detection, and the spectroscopy of an Earth-like planet.
