15. X11 Colors

PlantUML follows the web colors, which incorporate a subset of X11 color names. The X11 colors are especially useful to visualize color ranges.

Here are some tables of X11 color names based on the X11 rgb.txt. If a white bar appears next to the attribute PUML, the color name is not supported in PlantUML (e.g. NavyBlue).

When in doubt, use the hexadecimal color code.
