What is Petalica Paint?
Petalica Paint is an AI tool designed to automatically add colour to black and white sketches and line drawings. It's aimed at digital artists, illustrators, and hobbyists who want to speed up the colouring process without doing it manually. The tool offers several preset colouring styles, each producing a different aesthetic, and allows you to guide the AI by suggesting colours for specific areas. You can also simplify complex sketches before colouring to improve results. The service is accessible through a web browser and integrates with Pixiv Sketch, making it convenient if you already use that platform. It works for both personal projects and commercial work.
