#506 Node and circle connection bar colors are different

[Bill & Annie]

The node command and the circle connection bar option interpret the cyan-color from xcolor differently. The circle connection bar shows it more as I am used to. The node color is more what I would like to have.

My work-around was to overlay the connections with paths that had black mixed into the circle connection bar color.

Thank a lot for the wonderful mindmap functionality and all its diverse options!
