Abstract
A color detector includes a light source, a first filter, and a first photodetector. The light source generates light within a spectrum of wavelengths. The first filter is in optical communication with the light source and is configured to pass light within a first predetermined spectrum of wavelengths. The first photodetector is in optical communication with the first filter and is configured to output a first color signal if light passes through the first filter. The photodetector has an area configured to equalize the first color signal and maximize a signal-to-noise ratio of the first color signal.
