By default, the HotForeColor property is -1, which indicates no effect (use Color.Transparent for /NET assembly). The HotForeColor property sets the foreground color for the page's caption while cursor hovers it. Use the ForeColor property to change the control's foreground color (this apply to captions of the pages, not not inner controls). The HotBackColor property sets the background color for the page's caption while cursor hovers it. The HotObject property retrieves or sets a value that indicates the index within current tab-skin, that changes its background while the cursor hovers the page.
