I expect the use of the word 'anthracite' from a fashion designer or interior designer or decorator.
But from a football team?
Our colors have always been crimson and gray. This could be considered 'dark gray'. But anthracite - I had to look it up.
Regardless - hope they win! :-)

One hour from kickoff! We will be in the Crimson helmets with anthracite jerseys and pants!
