Whoever is in charge of Manjaro's styling needs to be throttled a bit.
They've been over saturating the colors more and more with each release and now it just looks bad. The icons in particular just look awful.
Certain apps grossly misuse colors too, such as Pamac, which uses different shades of the same shitty neon-green. I'm guessing it's a bug but maybe the designer handling the UX doesn't understand color theory or something.
It's just weird because the previous color scheme was fine - darker colors based around the familiar Manjaro green.
Functionality wise, Manjaro is alright. There were a few issues but nothing major.
The best thing about Manjaro is that it supports Snaps, Flatpaks, AppImages, and the AUR. I'd wager that if an app runs on Linux, it is available on Manjaro out of the box. Look at where Linux was 5 years ago, this is a massive accomplishment.
