1. A spectrum recovery apparatus configured to measure the color of a sample comprising:
at least one light source configured to illuminate the sample;
at least one light sensor configured output a signal that includes plurality of channels of data in response to light emitted by light source and incident upon the sample being received by at least a portion of the light sensor; and
a processor operative to:
receive the signal,
calculate an adjusted spectrum for the sample derived from the signal and at least one calibration factor, where the adjusted spectrum is a vector that has a larger dimension than the plurality of channels of data,
output the adjusted spectrum of the sample to at least one output device that is configured to receive data from the processor.
