The text I'm asking about comes from a brochure selling pens with bodies of traditional decorated Imari porcelain. Here's the pen design, with its name:
From another brochure, I gather that the reading is: おうりょくさいかぶとからくさ.
I understand that 黄緑彩（おうりょくさい） describes the yellow-green color, and 唐草（からくさ） describes the arabesque pattern. But what's the 兜（かぶと） doing in there?
I have a theory that it might refer to a plant called 鳥兜（トリカブト）, but I can't confirm it.
