Tags or color labels can be used to organize, filter, and visualize information. You can categorize your records and identify them quickly. Tags are personal: only the users who added them can see them on the records.
The 
button displays the tags column.
Filter the cards by tags.
Assign an existing tag to a card: right-click on the row, select 'Manage tags,' then click on an existing tag.
Add, remove, or modify a tag: right-click on the row, select 'Manage tags'
"To add a tag: Name it, choose its color, 
Check if you want to share this tag with all users (if not checked, you will be the only one using it)."
From the card, you can consult
or manage the tags. If multiple tags are selected for the same card, its color is black.
