what exactly each color mean?
i can easily recognize that the red is the active portion of the frame (the one that can hit)
violet can be the autoguard since takuma have some autoguard frames on that move
I don’t know anything about that game but that move could have different hit and throw vulnerabilities. A dumb example is in 3s, Seans EX Uppercut has complete invulnerability to everything but throws for a brief moment.
That’s just the only option not posted but someone who knows more about that game would probably know :]
One of them might be the “push” box, the box that deterines what part of a character is solid and can push the other character (or vice versa) when they move against each other.
