The StoryLucent Node editor allow any and every node to be customer colored. The design decision behind the coloring nodes is extremely important. A story is generally created through words but more information without a doubt can be conveyed through pictures and colors.
StoryLucent’s methodology is to provide the most flexibility to adapt the the design principles of the writer/creators needs. For myself I use colors to convey information such as emotions and also signal importance. As an example the brightness of colors can be used to highlight the most active points in the path. While the actual color red may be used to identify an action scene while yellow is a happier scene.
Of course because the color can be used anyway and the same color can signify many different meanings depending on the context of the node. I consider color an overlooked feature of any tool that can provide more facets of information for little to no cost.
