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

• Auto: The visual will apply the same color for all uncategorized nodes, and different colors for each node category (if you have created at least one category). 
• Fixed: The visual will apply the same color to all nodes. Selecting this color mode will reveal 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.
