All of the control bar styles on the palette are of subtle and well-crafted colors and shading. They will fit seamlessly with literally every design style imaginable by professional designers and developers as well as the more pedestrian users.
Differences are available in both color and texture. Colors are of every major base of the rainbow to be able to either fit or contrast perfectly within color families. Textures are either flat two-dimensional or a shaped three-dimensional feel arrived at by perspective shading.
