Blue Corn and Yellow Corn masa for making tortillas

Where can I get blue corn masa ready to go for tortillas, and is there a blue corn masa prepared a for tamales?
What about Yellow Corn masa prepared for tortillas and prepared a for tamales.
I do not like the white corn. Thank you in advance.

How about going super oldschool and deep with it?

I was hoping to get prepared for tortillas already. I do not know the right texture and such, and sometime not time to play. TY
