The basic principles of heterochromatic extinction show that the approach used in the visible should not work well in the infrared, where molecular line absorption rather than continuous scattering dominates the extinction. Not only does this extinction change very rapidly with wavelength (so that stellar color becomes only weakly correlated with effective extinction), but also many of the lines are saturated (so that Forbe’s curve-of-growth effect is much more severe in the IR.) Furthermore, broadband IR colors are more undersampled than those in the visible, so aliasing errors make them correlate even less with extinction.
