Hi.
Here is my Blender 2.5x Theme. I still use (for work) the branch of Blender 2.4 and I am quite satisfied with old GUI colors (especially regarding the 3D view). So, this theme has a very similar 3d view colors (object + selection etc.) lighter interface, hidden sliders and buttons with no shadows. My goal wasn’t to do a complete redesign of old 2.4x colors but rather to set the main colors of interface as I am used to it.
“My goal wasn’t to do a complete redesign of old 2.4x colors but rather to set the main colors of interface as I am used to it.”
2.4x theme included in Blender 2.62 is unusable to me. So, that’s to reason I use this one.
Maybe I should call it: “On Blender 2.4x based theme”.
