I don't think he's claiming that Champion Puce Swirls is a marble name.
Puce is just being used as a descriptive word, I'm guessing. (Am I right?)
Of course, it's not a color name that I'm conversant with. I had to google for it. I would just say purple for what I'm seeing on the screen.
If we can get past the name of the color, does anyone recognize the maker of the marble?
