Use highlightgroups command to search one or more columns in the Link results and highlight specific groups. You can optionally assign a priority to the highlighted regions. The priority would be used to color the regions. You can also explicitly specify a color.

For example:

* 
| link Label 
| highlightgroups priority = medium [ * | where Label in ('Log Writer Switch', 'Checkpoint Wait') ] 
| highlightgroups priority = high   [ * | where Label = 'Service Stopped' ] as Shutdown 
| highlightgroups color = #68C182   [ * | where Label = 'Service Started' ] as Startup

See highlightgroups.

Optionally, you can merge the highlighted columns to create a single column:
