John,
My front door panels from Legendary have carpet inserts described as "carpet #81 Charcoal". And the carpet I ordered from ACC was color 35 Graphite. When I ordered my door panels I asked about the source of the carpet for the inserts and was told it was ACC. Sounds like what they're quoting is right, but you might confirm with them that the carpet is from ACC and the color is Charcoal.
Good luck!
Chuck
