Gets the theme color of a component.
This property controls the appearance of highlights, appearance when a component is selected, and other similar visual cues, but it does not have any effect on the regular borders or background colors of the component. The preferred values are haloGreen, haloBlue, haloOrange, and haloSilver, although any valid color value can be used.
The default values of the rollOverColor and selectionColor styles are based on the themeColor value.
The default value is haloBlue.
