Now it still only changes the outline colour but I've found it rather helpful to add some colour.

These new icons are Scalable Vector Graphics commonly called SVG. The new icons are called Photon icons which only come with an outline. So a new solution that provided scalable icons which operated for contrast requirements and could offer personalised colouration was required. It is understandable that trying to use Thunderbird with a blurry icon issue is not exactly providing a product that is inclusive for all people. For others the icons were a predefined colour which some found almost invisible. Not everyone has the same screen resolution nor same monitor size nor same eyesight and the old folder icons were PNG images which were not scalable and for some people this caused issues and the icons became blurry.

Some info to help explain what has been going on behind the scenes in developer land and why they were put into the position of finding a new solution.
