Press space.
Comment what you like, it's all true. But all mean comments will be reported, for they, quite unlike recolors, are against the Scratch Community Guidelines. Just a note: There is only a single way to stop recoloring. Unshare all of your projects and get everyone else to do the same. Because when you click 'share', you are basically saying: Here everyone! This is my project! Feel free to comment, remix, and recolor it!
