I could have worded that better. The mention was in an email from my salesman telling me how my 2019 Signature would be different from the 2021.5 Canadian model, which seems to be essentially the 2021 US model.
I had noticed earlier that MazdaUSA.com still refers to “Caturra” but Mazda.ca now call the brown “Cocoa”. The salesman said the color was a little lighter and “browner”, but I haven’t seen one myself.
