I knew I'd written a utility to do this and I've just stumbled across it again by accident. It's on flightsim.com as nightclr.zip; it lets you select the colour for both the unlit panel background and the lit instruments, then writes the resulting RGB figures to the panel.cfg file. If the COLOR section doesn't exist, it creates it.If anyone wants to move it here....-Dai

Thanks for the tip.I just discovered that my FS Panel Studio will do something like this too. Although he should have done it more like how we do gauges. I'll suggest this to him.Patrick
