To assign a color to a tag, right-click the tag in the Tag Selector and select “Assign Color…”. In the pop-up window that opens, select the desired tag color, and click “Set Color”. Up to six tags can be assigned colors. To remove a color from a tag, select “Remove Color” in the same pop-up window.
Items that carry colored tags show small colored squares (in the color of the tags) in front of their titles in the center column. Colored tags make it easy to quickly scan a collection or library and see which items have been assigned a certain tag. And since colored tags are grouped together at the top of the Tag Selector, they are always within grasp.
