Choose which color mode is used for this node category. Color modes affect the way how node fill color is determined for each node or node category.

• Auto: The visual will automatically select and apply the same color for all nodes within this category. 
• Fixed: The visual will apply a custom color to all nodes within this category. Selecting this color mode will reveal Node Fill Color setting to choose your preferred node color.
• Dynamic: The visual will use data from Source Node Color and/or Target Node Color fields to apply node colors.
• No Fill: The visual will apply no fill color, and the nodes will appear completely transparent. Not recommended unless Enable Outline is On.
