Yeah, «e» is pronounced like the "ee" in "beet," while «é» is pronounced a bit like the "e" in "bed." :) Plus, «entre verde é branco» would sound kinda silly and nonsensical: "Between green is white" :D
Lol, yes, but, colloquially, both "white" and "black" are colors, even though they are not scientifically. I would not call forest green "creamy." I guess I was just thinking of pistachio ice cream. :P
Ugh, I guess I could imagine someone colloquially saying "between green and white," although I don't think I've ever heard anyone say it. Nobody says navy blue is "between blue and black." They just say it's dark blue.
If you scroll all the way to the bottom and click on "[show]" for "Shades of Green," I could totally see myself saying that "mint cream," "honeydew," or even "malachite" is a mix between green and white. (:,( tears because there is no celadon included in the catalog)
