Click Hide/Show for the BOM section that you are working in, and select the corresponding checkbox for Colorways.

One column for each color appears. You can use this column to update the color for a given colorway. Depending on the color control mode of each material, the options for selecting colors in each cell may vary. Both the Existing Only and Palette Only – Create Material-Color modes provide you with a list. The Uncontrolled mode allows you to either type the color or use quick search. For more information, see the “Color Control Mode” section in Adding Colors.

You can also add colors using the color clipboard. Press CTRL and left-click the mouse to add the color currently on the color clipboard. Colors added to components obey the color control mode of the material to which they are added.

If you expand the Colorways rows, the overrides you created at the top-level component row appear in the rows. They do not have to be recreated when you expand the Colorways rows.
