I'm not active on Colors! anymore but I have great memories of drawing with this. It was my first introduction to digital art when I was younger. Very simple with few tools yet there's no limit to what you can draw on it and I love that type of software. Same reason I've had so much fun using Windows Paint for drawing. I like minimalist software that can still create almost anything with enough work. I would say the only real limit that can stop a drawing idea from materializing is the small resolution and canvas size. Seeing the layers in 3D was very cool and the playback feature on the online galleries can teach you a lot about how artists go about creating their work. These days the app is on the Switch as well. I don't own a Switch, but I've heard that version has more tools and features, minus the 3D.
