Hi @GSquillace-EPMO ,
According to your description, I made a sample and here is my solution.
Create a column to rankx the left-most column.
RANKX ( 'Table', 'Table'[Column1],, ASC, DENSE )
This will distinguish the consecutive rows that have the same value.
And then you can set conditional formatting -> background color for your left-most column.
I attach my sample below for your reference.
