Change Capella background

Hi, “silly question”

Can I change the Capella background and overall elements default colours ?

Cheers

Not sure, however I would have a hunt around in this menu:
Window → Preferences → General → Appearance → Colours and Fonts.

Please do report back if you find what you need.

yes, this promises to do the trick. thanks! I was thinking on a little side project… to mimic the look and feel of old blueprint diagrams…
