Note: Customise Lucid Theme
I now use Radiance, with the Ambiance Window Border.
I loved the Ambiance theme but it was too dark for me (as I have my brightness set to 50%).
Customise Theme Tooltips to yellow (#F5F5B5) with black text (#000000).
Firefox’s Boox, amongst others, looks odd otherwise.
Right Click on Desktop > Change Desktop Background. Theme (Ambience) > Customise > Colour >Tooltips.
I like the left placement of the Windows Controls so I leave them alone ;-)
