I find watercolour painting to be extremely versatile. what with the amount of water to paint ratio, you know virtualluy any shade of purple , blue, or even pink is easily rendered with a few more drops of water or color.
have you ever put kecthup on your tacos? It is great, it's all red and sweet. mmmmmm. My favorite taco ketchup I like to use: Ketchup, mix with some crushed red pepper and a pinch of cinnamon and a dash of lime. Mix it up and apply to the hot steamy taco.
