Number of unique types of red blocks: 18 (not including the undefined reporter) You may be familiar with the red undefined block that you get by backpacking a custom block and taking it out. But did you know there are other red blocks? They got taken out, and their function might have been removed, but the blocks themselves are still coded into scratch.
In 3.0, the undefined blocks (and --) got deleted and the others got set to their proper colors. So yeah.
