I see, thanks.
I assume by your description of the caveats that you're changing the 
dialog that has the list of filters. I'm not sure I like the idea, 
since the background is already coloured by the filter colouring. That 
is useful to check that the colour combination you have chosen is both 
readable and not glaring, and also as a reference to colours you have 
already used.

On the other hand the 'edit color filter' dialog (which appears when you 
hit Edit) could keep the name of the filter in the filter colours and 
colour the filter string as you suggest. My apologies if that is what 
you did.

Whichever it is, I would like to see the initial colour of existing 
filters set consistently. That's probably only another line or two of 
code.

(I probably sound unreasonably proprietorial; I did add some code to 
that dialog, but I wasn't the last to do so and to be fair there are 
probably other opinions out there.)
