Updated August 20th, 2018 because I realized I accidentally removed the Repeat Button from the Transport Control, so I replaced it. Of course, you'll need the SWS Extensions and extract PT125.SWSColor from the archive to a folder beforehand. To pull up the custom colors, go to Track Color>SWS Track Color>Show Color Management, then select Load Color Set from File.
Also, I included a Pro Tools Custom Color Set for SWS Track Colors.
Originally, I had it as Pro Tools has it where only the Track Name background turned white, but I've noticed several people request a selection highlight.
I also adjusted the selection highlight in the Mixer. Updated September 1st, 2018 to address the look of the Master (thanks to for bringing it to my attention). PLEASE NOTE: This theme was created on a desktop PC with a screen resolution of 1920x1080 and it's also recommended to at least have a dual-monitor configuration to be sure the elements sit in their proper places, although a single monitor at the above-mentioned resolution can work if setup similar to the screenshot below. A theme I created by modifying the Albert-C Pro X Tools theme and skinning it to look more like Pro Tools 12.5.
