Custom Icon - which resolutions?

[cat]

Hi!

I want to create custom icons for my game and setup but the question is:

Which resolutions/color depths are required/recommended?
Can I use 16bit for all resolutions or do I have to provide versions with lower color depth?

Thanks, cat

I'd recommend the following resolutions:
16x16 - taskbar icon
32x32 - legacy icon size
48x48 - modern icon size

For the first two I'd recommend to also include lower colour depths (4 and 8 bit) for legacy reasons.
