TabPage objects and UserObjects when they are tab pages
The TabTextColor property allows you to select the color for the tab's text.
To add your own colors to the color drop-down list, select Design>Custom Colors before displaying the Properties view.
Select the desired tab page on the tab control.
Select the TabPage tab in the Properties view.
Select the desired color in the TabTextColor drop-down list.
The TabTextColor property takes a long value (-2 to 16,777,215) that specifies the numerical value of a color. The TabTextColor value is a combination of values for the red, green, and blue components of the color.
If you do not know the long value for the color, choose Design>Custom Colors to determine the red, green, and blue values and then call the RGB function to specify the color in a script. The following example sets yellow as the text color for a tab.
tab_1.tabpage_2.TabTextColor = RGB(255, 255, 0)
