EDIT: Looks like I am slightly colorblind and these ones are green too. They just look a bit different.
Looks like I actually got two different lots! I ordered 12 and ended up 5 red primers and 7 blue ones! I ordered a day or two after they posted.

Also I found it interesting to note that the red ones have a slightly longer COAL and/or case length. I assume due to the different manufacture’s or whatever.
Projectiles look the same.
Here’s the red headstamp for the curious:
