Potential User Interface Changes With Google Chrome v46 to v47

I noticed this morning when my Chromebook upgraded to the latest version 47.x (Beta) that the Folder icons at the top (in my bookmarks bar) are all dark gray:

In my Chrome browser on Windows running the latest version 46.x the folders are "yellow-ish."

I am sure there are other changes planned but this one really stood out.  I'm sure I'll get use it in a day or so.
