Thank you**

You can drag that same dimension on the Color mark in the Marks area, which by default is displayed below filters, right to the Data area.

To change the colors that Tableau assigns by default you can click on the Color mark and use "Select Colors": it will open a window where you can select the color you want for each value of the dimension you're using.

Edit

Unfortunately you cannot color the background of a dimension axis. You can achieve the same result with a trick though:

1. Drag the dimension to rows


2. Double-click in columns and write MIN(1)
   


3. From the marks dropdown, make sure Bar is selected


4. Drag the dimension to the Color mark


5. Drag the dimension to the Label mark


6. From the Label mark, set the horizontal alignment to either left or center


7. From the Label mark, mark the flag to allow labels to overlap other marks


8. From the Size mark, crank the size all the way up


9. Right-click on the dimension from the rows area and unselect Show Header
   


10. Right click on the MIN(1) axis below the graph, click Edit Axis, select Fixed among the Range options and fix start and end to 0 and 1 respectively


11. Right click on the MIN(1) from the columns area and unselect Show Header
    

Of course adjustments can be made to better suit your needs, but this should give you an idea of the whole process.
