It's more of a commentary about how food in the US is overly colored for no other reason than it looks cool, sometimes at the detriment of the health of the consumer.
"Concentrated carrot juice (for colour), Anthocyanin, Annatto, Turmeric, Natural flavour, Concentrated watermelon juice (for colour), Concentrated blueberry juice (for colour), Concentrated huito juice (for colour)" etc
From their ingredients.
My understanding is that a lot of food is colored to look "natural" for uniformity. A good example of this is applesauce.
