Nope. :/

Excuse me, I'm trying to apply this to my project, but I would like to make it only affect the background and tiles, if possible, not sprites. How would I change the code to accomplish this?

For the record, I have gotten it to work automatically, and with timers I've made it so it only shifts the hue a certain amount back and forth, it's just I don't know how to make it discriminate between sprites and background/tilesets. That's what I need help with.
