All I know is in perl mode,
$$, $@, $bla
BB, BB, BTTT (Black, Tan)

So it should be
BT, BT, BTTT like Shell-script mode,
or
BB, BB, BBBB
or
TT, TT, TTTT.

Sure they can -- they're different languages, even if they use the same
symbols.

One must be wrong. They can't both be correct. I just don't know which.
Or maybe both aren't correct. Anyway their syntax can't be that
different.

Anyway, no matter how you look at it, there is at least something wrong
with at least one of items in at least one of the modes!

If you say one item looks great, then you have to explain how another
item can use a different coloring rule.

Is this about Perl mode or shell-script-mode?  In Perl mode, all the
four $'s look the same to me.

The "bla" has a different colour, but I'm not sure why you think the "$"
should have the same colour as the "bla".

Looking at
print $$, $@, $bla
in Shell-script mode and Perl mode:
At least all three leading $ should look the same in the same file.
And they should all either be the same color, or different colors, from what
follows them.
So Perl mode has some work to do.
