When I was 4 or 5, I loved to read the ingredient lists on the backs of food packages, boxes, wrappers, etc. Something I saw very often was "Red no.1 Lake" or "Blue Lake".
Of course, it made perfect sense to me that they added an entire lake full of red or a lake full of blue.
What else could it mean?
