For those that like to collect variants, I just noticed that Hasbro has updated the paint application on The Black Series 6-Inch 34: Darth Revan figure.
• 1st release. (DS 62701) - Red paint used on Helmet.
• 2nd release. (DS 81281) - Dark Maroon paint used on Helmet.
Also it looks like Hasbro has updated some different shades of silver and gray as well on the helmet, but will have to confirm after I open one of the newer ones up.
Personally I think the newer version which I just got from Entertainment Earth looks much better then the older version.
Anyways you can view a side-by-side comparison pop-up photo above or visit the figure's page for larger photos.
