Very hard to change if you want to change it's color scheme. Just from admin control panel you can change very very few things. If you really want to customize this theme then you have to dive deep in CSS which is fine except the CSS it came with has many errors. I have ran a check for the CSS defining this theme with http://codebeautify.org/cssvalidate and it yielded a lot of errors, which shows that the quality of this theme is not good enough. Disappointing.
The themes made by OW Visuals are fantastic! The support though, is even better. I was having an issue with a plugin, and the way it worked with the themes. Not an issue that they are responsible for at all, but they still took the time to help me figure out the issue and fix it. I will definitely be buying more OW Visuals themes in the future.
