This theme is very close to the original Blender theme, but maybe a little more easy on your eyes.

I decided to release my theme to the public after using it for some time. I created this theme to resemble the original Blender theme but darkened and flattened. I also took elements from the Graph theme. As I liked the style of it, but found it too high contrast in some areas.
If you have any suggestions please tell me! As I'm always looking for ways to improve this theme.
