Object Mode List
Use this list to switch a selected object between filled and stroked mode.
Channel List
Select an item from this list to draw on a single color channel. When you switch channels, the viewport updates to display the specified color or alpha channel(s) for the selected object(s).
The panels in the Color controls update to reflect changes made using this list. For instance, if you select the Blue channel from the Channel list, only shades of blue are available on the different panels, and only the blue portion of the selected object's color is displayed in the viewport.
