Hello everyone. I have been reading Graves' book for a week or so, got it from the library, and I've gotten to the first exercises but I wanted to clarify some things. In the first part of the book when he explains the elements of design he says there are "seven elements, factors, or dimensions." But later on when describing repetition he says there are six dimensions? Or does he mean there are six dimensions in use in repetition? Also this is my first real experience with color and I don't think I fully understand the concept of chroma, is it like the intensity of the color itself, like a very bright red or is there more to it then that? I apologize if these questions sound stupid as I've never really studied design before.
