I suspect that the IR issue seems to affect black colors more than
others is that the IR contamination of other colors is overshadowed by
the visible wavelengths they reflect. Black, defined as a lack of
reflections in the visible part of the spectrum, will show any IR
reflections much more than an object that is reflecting a significant
portion of the visible spectrum.
