i got inspired by the pen videos that appeared on scratch for a while. actually they might still be there but i haven't seen any new ones lately. i used something that separates images into their RGB channels, which stand for Red, Green and Blue, which are also the colours used in pixels to make the more detailed colours that you can see on your screen (magenta, yellow, cyan, etc). they make the detailed colours by merging red, blue green together (seeing the project might help you understand). here's the RBG channel decomposer i used to get the decomposition of my images: https://pinetools.com/rgb-channels-image
