Get an idea...from a book or magazine or movie or wherever
Go shopping through my stuff and pull out everything that speaks to the color theme in my head
This is less than 24 hrs into the process of making this book. Oh, I've done lots of other things in that 24 hour period, but this is what I have been making. The color pallette came to me fully formed, but the content is still unclear.
I gave myself the challenge of making this entire book from stuff I already own - I can't buy anything new.
I haven't worked in this pallette for a long time. I used to, and it feels very familiar, like a language I already know.
