To access your service categories you need to go to Manager > Categories > Service Categories.

This section will display all of your active service categories and their corresponding colors.

To edit the color associated with a category Single Click it so it is highlighted 'Yellow'.

Next select the Color option from the bottom panel. You will now be able to assign a color to this category. 

Note : All services set up under a category will inherit the color assigned to the service category.
