On this page you find all important commands for the CLI tool gvcolor. If the command you are looking for is missing please ask our AI.


gvcolor is a command line tool that is part of the Graphviz suite. It is primarily used for computing colors on drawings created with Graphviz.

The tool operates by assigning different colors to vertices or parts of a graph. It is often used in conjunction with other Graphviz tools like dot or neato for visualizing graph structures.

gvcolor uses various algorithms to determine the colors to assign, such as the spectral method, median cut, or an additional algorithm based on an approximate minimum vertex coloring.

This command line tool is highly customizable, allowing users to define their own color palettes and specify constraints for assigning colors.

The output of gvcolor is typically a color map file that can be used with other Graphviz tools to generate colored visualizations or drawings.

The tool supports a wide range of formats for representing colors, including RGB (Red, Green, Blue), HSV (Hue, Saturation, Value), and CMYK (Cyan, Magenta, Yellow, Black).

gvcolor can be used with both directed and undirected graphs, as well as with strict or non-strict subgraphs.

The tool can also handle cluster colorings and vertex shape/color information directly embedded in the input file.

Overall, gvcolor is a valuable command line tool for applying colors to graph representations, aiding in the visual interpretation and analysis of complex data structures.
