This specific case is not the one of "side-by-side" characters, but
the the case of _one_ character which is combining around a base
letter as two separate glyphs. These individual glyphs are those
that were used on typewriters, instead of the single abstract
letter. So on typewriters, you could color them individually, even
if they were denoting a single letter. There was then no key on the
typewriter keyboard to enter this character, and these glyphs had
the actual status of coded characters. Even the base letter in the
middle of the two combining glyphs will then have its own style
or color: this is the exhibited coloring feature in Tamil, where
the base letter is colored, but not its combining character that
follows it. On typewriters, there was simply no combining characters
but plain characters representing each part of the glyph and that's
why it worked.
