I was reading yesterday how blue is the inedible colour. Sure, fish can be kinda silvery blue and some cheese can have a bluish tinge, but it's being stretched.
That's why the Blue Wizards (and Gandalf probably) have not yet been devoured by predators. Their colour is off-putting. Unsurprisingly, the many Green Wizards who accompanied Gandalf et al over the Sea were swiftly eaten, possibly mistaken for cucumbers.*
