Ribbon with class grey doesn't have the correct color

I have noticed that the grey colored ribbon inherits the brown color. You can view the color at this class ".ui.ribbon.label:after" on key "border-right-color: inherit".

Proposed solution

You can replace the brown color by this color #a9a9a9

Version

2.3.2
