Support. To be more precise, I believe the ctype should occupy 33 bits; this allows 1 buffer bit, which is necessary since a ctype of 0 means no signal. Furthermore, the new 4 bits of ctype should occupy "infared" colours on the spectrum - the infared spectra are absorbed at lower temperatures, and reflected at higher ones (over a spectrum of, say, 0 to 80 degrees Celsius). (This both ensures compatibility and adds a cool new feature.)
