I have a few journals that I use for collage–I’ve posted some of the ones from the landscape journal–and these are from the one containing abstracts.
I took a book out of the library about Karel Appel a few months ago, and was attracted to his dark paintings from the 50’s. A lot of his work is colorful and childlike, and I have an affinity for those, but the abstract expressionist-flavored ones he did while hanging out in Paris with de Kooning and Pollack seemed ripe as inspiration for collage.
I didn’t make copies of the exact paintings I used as reference, but found plenty on the net that give a flavor of what he was doing at the time. In echoing the work of someone I admire, these explorations always allow me to see color, space, and form in fresh ways.
