This color stuff is fun. So why not press on a little? I’m on the road so I can’t bake, and I have a fair amount of waiting around to do. Sounds like a recipe for jabber, no?
Blue No. 1, also known as Brilliant Blue FCF is one of the most popular colors in the world, but most people hear very little about it. Why? Because it doesn’t appear by itself very often. It’s mostly used in combination with others, especially Yellow No. 5, to make various shades of green. The reason for that, because blue is something of a turn-off when it comes to the human appetite. In fact studies have show that we’re instinctively averse to it.
Whereas bright reds, yellows, oranges and greens signal ripeness to our brains, colors in the blue, purple and black family signal the opposite. Molds are blue, fungi are blue…the often toxic stuff that grows on old food as it rots. Yuck. And so we’re disposed to avoiding that color. Blue and purple hues have been proven to suppress hunger, which is why dieticians frequently counsel people who wish to lose weight to eat from blue plates, or put a blue light bulb in their refrigerator. Somewhere, something deep down inside us says “blechhhh”.
Blue also isn’t used that much because, to be frank, it comes out fairly unchanged on the far end of our intake pipes. Exactly why is a bit of a mystery, since other than looking different, most pigment molecules have very similar structures, and should at least theoretically digest the same way. But changing a toddler’s diaper after they’ve eaten a big bowl of a Boo Berry cereal can be an alarming experience. It’s why my daughters now eat Cheerios.
