A theme originally adapted from Ubuntu Ambiance, focused on stripping down UI colouring and styling elements down to it's core, to create a simple. logical and clear theme, with a sharp colour highlight.
Greyscale base with a unified colour range (Purple!) for selections and interactive elements
Silhouette ticks for tick boxes and flattened UI elements to create a more monolithic appearance.
Some areas still need tweaking as I dont use all the UI areas within Blender, but it can be considered a complete theme for now :D
V1.01 - Fixed the tickbox, and adjusted some colours throughout the UI.
