It's a bit hard to figure out from your description (I guess
I should
try it out tonight) but if you are saying that every local
variable
has a different background color, then I definitely think
that is too
much "noise".

IMHO:
A single specific foreground color for all local variables
would be
nice (and also for member variables and globals, but using
different
colors) and
A single background color for the selected variable would be
extremely nice!

I think that would strike a nice balance between
"noise" and
information. I certainly don't need different colors to
distinguish
variables such as "name" and "timeout"
in a local context, the names
are more than enough for that. But easily locating all
occurrances of
a specific variable by selecting is very very useful.

I agree with all of the above.
