I have a Betty in "Fox" and it a gorgeous tan/whiskey sort of colour that looks nothing like that web picture IRL. I will be taking a picture soon and will post here for your reference.
As long as "Fox" on a Silverado is the same as "Fox" on a Betty then it will give you a much better idea
That might sound strange but I have seen a Cannelle Quilted Bay and that colour is vastly different to Cannelle on a Paddy ush:
