Is your feature request related to a problem? Please describe.
I'm always frustrated when working with official icons with transparency in light mode because the background color is always black, making it difficult to see the icons properly.

Describe the solution you'd like
I would like the background color for transparency to change based on the selected theme (dark or light). In dark mode, the background should remain black, and in light mode, the background should be a lighter color that makes transparent icons more visible.

Describe alternatives you've considered
An alternative solution could be allowing users to set theme-specific icons for models. This way, users can upload different versions of icons that are optimized for both dark and light themes.
