By default, Colors for Jira places a small colored tag around issue keys. You can also choose to highlight entire rows:
![](/documentation/colors/files/latest/197952089/197952090/1/1710185234000/Highlight+whole+row+-+dropdown.png)
To change from one mode to the other, toggle the Highlight Whole Row option in the dropdown menu. The selected coloring mode applies to all Jira pages.
