Let me just say something first that has nothing to do with cookies or color or anything really that you would ever care about -- I am a vegetarian.
Now that we've gotten that out of the way....Let's talk about South Korea again, shall we? When we first moved here, going out to restaurants was like a game of Chance. My husband and I would randomly point at items on the menu and hope we liked it. (For the record, we are, in fact, reasonably sane adults that have somehow made it to this point in our lives by making actual decisions.) We just didn't speak Korean. We had no way of knowing what we would end up with. My husband got octopus and I got something that looked like spaghetti but instead of tomato sauce, it was hot red pepper sauce. We have also ordered neck bone soup, intestines, and once we even ordered a hot dog without realizing it. I may have lost 12 pounds in the first 2 months that we lived here.
We eventually figured out how to read Korean and then each time we ordered something new, we tried to figure out what words were the same as something else we had ordered and if they had any of the same ingredients. Then one day, we got a book that had pictures and told us what everything was and we all lived happily ever after.
Making icing colors is kind of like eating out in South Korea. If you don't know how to mix red and yellow to make orange, you are going to end up losing 12 pounds. No wait...that's not what I meant. What I mean is, you need to know what is in your food coloring so you can make the color you want.
Do you remember that one time I was talking about making pink icing and we wanted it darker so I said to add brown, because it has an orange base? Yeah...that didn't make sense to a lot of people. It took me a long time to realize that Americolor Chocolate Brown had an orange base. But it took me a lot less time to realize that black has a purple base to it. I mean...have you LOOKED at your hands after you get black food coloring on them?
The way I see it, you have a couple of choices to make. You can spend the next 4 months analyzing what happens each time you add a certain color to a different color and see what patterns you find...OR...you can get a "guide" to the color bases of your food coloring.
Also, you can either do this yourself, or let your children do it. You know, in the name of "education" and "providing quality learning activities in the middle of summer when all your children want to do is lie on the couch and stare at the ceiling and complain about how there is never ever ever anything to do besides lying on the couch and complaining."
So...you know...your choice.
You need some seriously fancy equipment for this -- a bowl of water, food color, and a paper towel. Email me if you have any trouble acquiring these items. I can give you a list of suppliers.
I ran out of attention span before I could do anymore. Feel free to put your children to work and see what your own favorite food color shades are hiding!
