I also decided, for my own sanity, I had to write a list of my various color combinations. As I mentioned earlier, I'm using the cool colors - blue, green & purple for my chains and warm colors - yellow, red, orange & pink for my circles. Now, you are certainly welcome to say, '... sure, Capt. Obvious', as my daughter would say, but it's helping me & thought it might help others who are doing a scrappy version of our project.
