What does 兜 mean in 黄緑彩兜唐草?


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.




I think that 兜唐草 is the name of a particular arabesque pattern by 源右衛門, a
well-known pottery store. In particular, this pattern:

The imagery of 兜 is being strong or forceful. In that sense, 兜唐草 seems to be
well-suited as a name for fancy accessories like a pen or a wallet. (The name
for pattern for a plate or a piece of cloth might be more something like 雅唐草.)

I don't think that the choice of 兜 is related to トリカブト, the aconite plant, as
there is no particular resemblance of the pattern with the aconite plant.
