1. An apparatus comprising:

  • a treated tape;

    an adjustable color source emitting a first radiation toward the treated tape, the source operating at each of a plurality of different target wavelengths in a spectrum;

    a photodiode measuring second radiation reflected from the treated tape; and

    a processor analyzing measurements from the photodiode to determine a peak wavelength from the plurality of target wavelengths, and based on the peak wavelength, determining a color and darkness of a color stain on the treated tape.
