Hmm... This technique can actually be done by putting a background of your choice behind a white background, you can customize the white background to display texts, and other drawings of your choice, and the best part, you can make the color of the background behind the other one different colors too. But the hard ones are, you need specific and complicated rules to pull this off, if you want to do rainbow, or white grey black forward screen That kookoograce is how you made the simple thing you did actually, nice job
