User:Rcorrigan/AHGW Pro:HGU Color Manager
The HGU Color Manager pane is accessed by selecting 
HGU Color Manager on the Arc Hydro Groundwater ribbon in ArcGIS Pro.
- ArcGIS Notes – In ArcGIS, the HGU Color Manager dialog is accessed by selecting Subsurface | HGU Color Manager from the Arc Hydro Groundwater Toolbar. It can also be accessed via a button at the bottom of the Borehole/Well Editor dialog.
This dialog allows for managing the symbology of layers based on a common attribute using a single interface. The tool is based on the "HydrogeologicUnit" table which defines a set of conceptual hydrogeologic units that are associated with different spatial instances such as volumes, cross sections, borehole intervals, geologic picks, and outcrops.
- Source section

- HGU ID Field – Allows for specifying of which column in the table will be filled in for the HGU ID column in the spreadsheet in the pane.
- HGU Name Field – Specifies which column in the table will be filled in for the HGU name in the spreadsheet in the pane.

Clicking on the Color Properties button at the bottom of the menu, opens a Color Editor dialog with advanced options for adjusting the color associated with the selected HGU.
- Apply Symbology – Click to immediately apply the changes made in the spreadsheet.
