property MarkTime.StatusEventBackColor as Color
Specifies the background color or the visual appearance of the events (status) that intersect the timer.

TypeDescription
Color A Color expression that specifies the background color to show the status of the events that intersect the timer. The last 7 bits in the high significant byte of the color to indicates the identifier of the skin being used. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the background's part.
By default, the StatusEventBackColor property is 0, which means it has no effect. The StatusEventBackColor  property has effect only if it is set on a non-zero value, and it changes the event's status background color (StatusColor property) for all events that intersect with the current timer. The StatusEventPattern property specifies the pattern to be shown on the status part of the event. The BodyEventBackColor property change the event's body background color. The ShowStatus property shows or hides the status part of the event.
