Confidence: I'm as sure as I can be.
Notes: the contrasting colours of the Red and the Yellow Pimpernels accurately reflect their opposite characters.
Scarlet Pimpernel(echoing Orczy's hero) is bold, brave and dashing. it defiantly stands up to the full might of open-aspect, solar oppression. often the lone hero on bare ground.
whereas, cowardly custard Yellow Pimpernel is found in the opposite aspect.
like an army deserter living in constant fear of being exposed, it hides itself away deep in the anonymity of the shady woodland crowd. it creeps along the ground furtively, trying to pass itself off as a local Buttercup.
