So in Color, Form, Production we began our Itten color wheel, and it was a process. I have taken color theory classes before, but never have I used the numerical values to determine the correct color. The math wasn't too difficult, but I did have a minor freak out when all of my colors disappeared. They were still present on my layer, they were just completely invisible. Apparently, Command Y is all it needed to be found again. Which is good to know for future reference.
The interactive websites are pretty neat. It allows to really see the relationship between the colors and how one color can look different because of the color behind it.
