R6 theme question-possible to have an item's colour only on the surrounding edge?

[musicbynumbers]

Hi guys,

I'm trying to get back to my "dark theme" roots

I'm using near enough the default 6 theme but wanted to know if it was possible to edit the item bng still to make it so the item (or track) colour only shows up on the item borders/edges rather than the whole item?

I had a quick look at the item PNGs in the unpacked theme tbu it's been so long I'm not sure what all the pink lines mean any more

I wanted to see what it would be like have it like below

-item background un-selected = Fully black
-item background selected = Dark grey

-item waveform = track colour
-item's surrounding border/edge = item colour


Is that possible? I know that I did this years ago and there were some issues where as you zoomed into the item either vertically or horizontally it would make the item surrounding edge more thicker but maybe that's not too bad to have a mostly black theme.

Thanks!
