Sometimes by accident, or by who knows what, TortoiseHg changes branch colors.
I tried to find in the documentation how to set branch colors explicitly, but it didn't worked.
I tried an extension named 'color' but don't know how to configure it.
It seems the Workbench settings UI can help with the correct syntax for the config file.
It can be used as documented: branchname:#HTML_Color, just need to put it in the correct setting name
What is in the config file at the end is:
branchcolors = Stable:#FC951E
, using orange for the Stable branch Stable:#FC951E
As documented officially, the value is SPACE separated list of branches.
Spaces and colons in the branch name must be escaped using a backslash (\)
