The > nodes with fillcolor = red do show up as red nodes. The code #ff0000 > should also produce red nodes. According to[1], the color element should be passed an ID, which definition follows: * Any string of alphabetic characters, underscores or digits, not beginning with a digit; * a number [-]?(.[0-9]+ | [0-9]+(.[0-9]*)? ); * any double-quoted string ("...") possibly containing escaped quotes (\"); * an HTML string (<...>). 1. http://www.graphviz.org/doc/info/lang.html BTW, the error message is quite clear: | $ dot -Tpng grey.dot -o grey.png | Error: grey.dot:4: syntax error near line 4 | context: 4[style=filled, >>> fillcolor=# <<< ff0000]; You just have to escape the string containing a '#', using " characters, and it just works.

Indeed, I think I just misinterpreted this from the manpage: or a "#rrggbb" (red, green, blue, 2 hex characters each) value at that time. The reason I reported this bug is that I never _saw_ that message, since I create my graphs with a program and the program doesn't check for stderr of graphviz. After the image is created I use a viewer to see it automatically, hence from my point of view everything was fine, except with Graphviz. I consider it a bug for a program to continue in the case of an error. It should abort when given nonsensical input. Don't you agree with that in general?
