Okee doakee. Let's forget, for the time being, the NLRs labeled Sunsets by Peltier in that nice nice box. Let's just think about the marbles that collectors call Sunsets. You know the ones I mean.
Why do you think the name "sunset" was chosen for that particular marble? Keeping in mind that most collector names for Pelts are color-combination names?
Because it was blue? Because it was green? I don't think so.
Maybe some collectors, for some reason, have tried to expand it into a "type" that's construction-based instead of color-based, but that's another issue. To me, anyway. If you want to define that type by construction I would suggest another name -- not a color-oriented one -- be used.
We could have a naming contest. Except for Galen, of course.
But mainly, after waiting so long for a green fizz to come to my house, I ain't callin' it no Sunset.
