Eric is using "bands" in a looser sense, indicating that the XYZ weighting
filters have their peaks at different wavelengths, and can therefore
be regarded as 3 (rather poorly separated and overlapping) "bands".
And just to follow up, some instruments (the Spyder) are
half way between, breaking the wavelengths up into a smaller
number of (presumably) partly shaped bands, that are then
further weighted / subtracted by the software. In theory
this may provide better display device independence without
the disadvantage the true spectrometer has of the XYZ weighting
shape being discretely approximated.
