Msot, if not all, CRT data sheets will include a graph of intensity
against wavelength for the phosphor, from which it's possible, at least
iheory to deduce the colour. How you relate that to the RGB values is
another matter...
And finding the data sheet for the CRT in a given terminal may well be
non-trivial.
