  1. It looks awful with dark colours enabled in Windows 10. Completely different to how it looks with light colours. Not that the above screenshots show what the theme is supposed to look like.

  2. It does not match my desktop environment :D

    Alpenglow is too colorful for me!

    I run most bright themes today. Tired of dark themes.
