What's new in version 1.2004ubuntu4:

Ubuntu-orange colors throughout are more distinctive and darker
Better text color definitions
Fixed window header bar color to better match with Yaru
The flash of purple for bookmarking and downloads is now darker and more Ubuntu-ish

Source theme: GitHub About Yaru: Yaru is a Ubuntu community theme that is shipped with Ubuntu 20.04 LTS. You can also install Yaru from apt repository. This theme adds a matte adaptation with the Yaru dark variation. It will be updated if the colors break when Ubuntu pushes new update to Yaru theme.
