In Photo viewer (NOT photo gallery) the command bar does not match the explorer command bar when you hover over the options, as well as the color is a bit off.
The color is a bit darker with more blue-ish hues.
When you hover over, the buttons are more fatter.
This has become a real problem with you guys not matching all of your command bars.

Please, just give some constancy here. Have ONE team work on the command bar (ALL of them) so you know you can get it right the first time.
