I would like to have a set of terminology definitions about colour started here...
I want to kick off with the question, "What is the separate meaning of tipo, aurea, alba?"
I understand that alba is the white variant.
I am not sure how tipo is defined,(or how it is different from what people call "the common form"), I think that aurea is mostly yellowish or white with a purple or pink or coloured lip. But that may be quite wrong.
I've read tipo to mean,"of the type" or typical.
but I see it used to mean something else sometimes.
Oh, let's add atropupurea and atroviolacea while we're at it, although I think those are kind of self explanatory.
Here we go!
