I’m a little late to this thread but...
I’ve got an early K2, in Briar Brown. It hasn’t seen much sunlight in the last 25 years or so.
You are correct, it is dark, DARK, kind of a root beer color. In the sunlight it turns brown, and somewhat sparkly, but not candy.
I hated it at first, but it has really grown on me.
I worry taking photos won’t actually be an accurate depiction of the color!
