how to change track colour on montana

In Basecamp, I have the track colour set to dark grey and on the screen they are dark grey. However, when I copy them to my montana using basecamp, they are all magenta. I'm not referring to the active track that is created while I paddle. That one, I can change in the montana. I mean the track that I am following from basecamp.  If this is a montana issue, I'm sorry to post here. However, is there a way to change the track colour on the montana? If that done through basecamp?  thank you
