gvcolor is a Graphviz filter that colors nodes in a ranked directed graph. It takes a graph processed by dot in canonical format and assigns colors based on node rank/depth. Nodes at the same rank receive similar colors, creating a visual gradient that shows the flow structure. Typically used in a pipeline between dot processing stages.

Input must be in dot canonical format (-Tcanon or -Tdot). Works only with directed graphs that have been laid out by dot.
