System monitor and colour blindness

Hi everyone.

First of all, apologies if this is the wrong thread.

I have been using the System Monitor and in general, it seems very usable and the presentation of the graphs is clear.

However, I am colour blind and the specific colours chosen for the network upload and download speeds are almost identical to me.

I have not found a way to change the colours. Is it possible to change the colours at all?

Ignore this, I'm an idiot.

If you click on the samples of the line's colour, then it brings up a colour editing window.

In my defence, I had no idea this functionality was there... pretty feeble defence, though.
