When people do studies of the effects of food coloring on children, are the children blindfolded?

That is, can the studies discern the neurochemical effects of coloring molecules from the psychological effects of eating brightly-colored food?

I expect that beige cookies are not as exciting as vividly orange cookies.

My read of the Mattes & Gittelman paper is that they're comparing natural and artificial food coloring.

Moreover, no type of rater (parents, teachers, psychiatrists, nor children) guessed beyond chance the type of cookie.
