I try just ends up with:

/usr/lib/ruby/1.8/tk.rb:2762:in `__invoke’: unknown option “-colors”

But all the documentation stats that it does have a colors option:

Ruby/TK - ProgressBar Widget

Supported options depends on your version of BWidget libraries.
Probably, your progressbar widget is old and doesn’t support
‘colors’ option.
You can check supported options and status of a widget by ‘configinfo’
method or ‘current_configinfo’ method.
If your progressbar widget is one of an old version, ‘foreground’
option can change its bar color.

Yes the foreground option worked. Thank you
