A variety of colours for the comment blocks

[NobodyX]

The comment blocks are helpful for visually breaking up walls of blocks so it's easier to parse what you're looking at. It would be nice if there were additional comment blocks that come in a variety of colours, maybe bright colours that aren't used anywhere else among the regular blocks. Or maybe just grey + black + white.

I'm not sure I like the idea of having a bunch of comment blocks with the only difference being color. However, the idea of being able to apply different colors to blocks does sound neat.
