How to change background color of SelectDirBitmapImage and SelectGroupBitmapImage in Inno Setup?
Solution
Hardly. Both those are icons with a transparent background from shell32.dll painted on the TBitmapImage using SelectDirPage.Color and SelectProgramGroupPage.Color long before any user code is triggered. It cannot be updated. You would have to repeat all the painting code in your Pascal Script. It's probably doable, but lot of work.
The relevant code is in LoadSelectDirAndGroupImages function:
