Looks good. I have just installed packages from your PPA to freshly installed Ubuntu MATE 22.04 LTS daily build by using below comands:
sudo add-apt-repository ppa:lah7/ambiant-mate
sudo apt-get update
sudo apt-get install ambiant-mate-colours-all
then selected needed theme from MATE Control Center → Appearance.
Now the system looks traditional and cool! Thank you!
Retrospective future is back!
