Redmine

I've just read the RedmineTextFormatting guide, and one badly needed feature caught my eye: syntax for changing text colours. I wasn't aware of this feature, probably because in the default text editor, there's no widget that would let me choose the colour; I need to be that by hand, by manually writing the markup.

Is there a plugin that would display such a widget? Redmine 2.5.2 here.
