I saw the process for making the tyrian purple (royal blue) dye on the show Worst Jobs in History with Tony Robinson. As for pink being mentioned that reminds me of this discussion:

Deconstruction the irrational associations with color.

Anger he smiles towering in shiny metallic purple armor
Queen Jealousy, envy waits behind him
Her fiery green gown sneers at the grassy ground
Blue are the life-giving waters taken for granted
They quietly understand
The once happy turquoise armies lay opposite ready
But wonder why the fight is on

My red is so confident, he flashes
Trophies of war and ribbons of euphoria
Orange is young, full of daring
But very unsteady for the first go round
My yellow in this case is not so mellow
In fact, I'm trying to say it's frightened like me
And all these emotions of mine keep holding me from
Giving my life to a rainbow like you

cochineals are used today in some foods so the manufacturer can claim that the product is A: Organic or B: Has no artificial colors.

You have been eating bugs and didn't even know it.
Not to mention that the FDA and the Canadian Food administration don't make it mandatory for companies to list Cochineal as an in ingredient.

Mmmmnnn.
