These two completely different techniques are often given different
names, with "false color" applying to the first and "pseudocolor" to
the second.

P.C. names for colouration now?

No they are quite different in concept.

One maps three separate monochrome images to the colour planes R,G,B.
(essentially to show distribution of different narrowband emission)

The colours used may bear no relation to the wavelengths observed.

The other adds colour to what was originally a single pure monochrome
image with the intention of making fine detail visible.

In my book they are both false colour images but usage varies a lot.
