3ds Max supports Windows themes. This means that when the user changes the color theme used by Windows, the user interface of 3ds Max will update automatically to reflect the changes to the Windows theme.

The majority of user interface (UI) controls in 3ds Max are drawn by Windows, bypassing older 3ds Max custom control drawing routines. This way the look and feel of controls is dictated by the Windows theme selected by the user.

If your plug-in manages drawing of custom controls (such as owner-draw controls) and you want that control to follow the Windows theme as closely as possible, you may want to utilize Microsoft's Visual Style API.
