It has been added last October, but only now i feel that it has been polished enough to have it officially supported and released. The latest 4.0dev drop of Substance provides full support for a new toned-down skin named Autumn. It is similar to the Creme skin, but even less intrusive. It is one of the two new skins that use the same theme for default and disabled controls. In order to differentiate these two states, a skin defines a custom alpha value (translucency) for the disabled state. The end result (see screenshots below) is that the disabled controls appear less “visible” as the default controls. This also means that if you set a non-null watermark, it will “shine through” the disabled controls.

Here are a few screenshots of different controls under the new Autumn skin. Buttons, toggle buttons, checkboxes and radio buttons in different states (default, selected, disabled and disabled selected):

Comboboxes in different states (default, active, disabled, with custom background):
