My preference has nothing to do with the color and everything to do with the taste. I like a strong lemonade with a round mouth feel (doesn’t make you pucker or cause any twinges in the mouth due to acidity). We used to have a Meyer lemon tree at our previous home, and in my opinion they make the best lemonade. I hate getting lemonade that is so weak that it looks like someone might have maybe passed a lemon slice near the glass, but I also hate lemonade that makes your jaws hurt because of the acid.
