Pro Grape is a dark gray/purple theme. I wanted something easy on the eyes and very clean/professional looking, so I went with square corners and some jazzy purples and blues.
I've tweaked this theme quite a bit, but there's always room for improvement. I hope you like this theme, and if you have any suggestions, please drop me a comment! Thanks ^_^
It looks good! I'm going to try it on 2.79
