The TimelineViewAppearance class introduces properties that specify how the view's visual elements, such as cells, selection, cell headers, etc. are painted. Each property returns a AppearanceObject object whose attributes specify the corresponding element's background and foreground colors, font settings, gradient mode, etc.
For more information on appearances, see the Appearances document.
