I don't know. That seems like a cool idea though. Then
you would see (i.e., not read) all the occurrences of
that variable at once. However I don't know how it
would work in practice. Perhaps you would just get
dizzy. With lots of parameters, perhaps it is better to
have them a uniform color, to make a really clear
separation what is data and what is metadata,
branching, etc.

If you were to put it up, I wouldn't recommend random
colors, instead you could use the variable *name* (the
letters) as function input to be mapped to colors: the
first letter - the ASCII position, "normalized" - could
be red, the second - same for green - etc.

First step if you were to do this would be to examine
how colors are setup to begin with. Instead of the
static color, you would hook a defun to calculate the
color based on the variable name.
