From https://github.com/PintaProject/Pinta/discussions/892, there are some improved icons that have been contributed. For macOS (and maybe Windows) we could ship these, replacing the default icons bundled with Pinta. This would need a bit of work in the build system scripts to set this up.
We shouldn't do this for Linux since the system GTK icon theme is being used
