A tag is a way of categorizing a Rindle board by type, represented by a color and a term.
There are 8 default tag colors to choose from, you can use the color picker to select virtually any color you want, or you can use a hex color. A single board can have many tags.
Adding and Removing Tags on a Board

From the menu, click on the tag that you would like to apply to the the board or search for the tag name. Add a new tag by typing out the name of your new tag and click Create Tag.

Colored tags will display on the board face and inside the board. Tags with no background color will only show inside the board.
