A good year for end of times yellow. Don't kid yourself about all this cowardice stuff, that all stemmed from the Spanish Inquisition when heretics where marked as yellow, same with Jews, traitors and anyone else who despite being frail and weak and usually a minority, didn't buckle under. When you think structure, think yellow and the way meaning slides through language.
Our word yellow comes from the Indo European, and in my view more civilized, side of our language where it meant to shine or gleam. My own preference is gleam and I'll tell you why. There's a flycatcher round here called a Phoebe. But there's no way a Phoebe's chest is allowed to be called white, because as a devil who has chased out generations of barn swallows, The Phoebe is both still and she gleams in dark places. There's Femme Fatale green to a Phoebe's white. Not to mention the associations between white, devil, Zanzibar and aimless wandering.
Anyway, Structuralism was fond in its belief that language had created a universal and stable structure of meaning, and would have described a Phoebe as a flycatcher with a white chest
