Conditional Formatting of Combobox Text Color?
When you say combobox, do you mean a dropdown slicer? It isn't currently possible to conditionally format the color of an item in a dropdown slicer. You'll have more flexibility with the new slicers which allow conditional formatting for the value and background color and an option to use a label instead of the column values as a callout. There's no dropdown equivalent though.
