Question about Wiki Shoryuken MK 9 guide

Hi guys,

I just started playing MK 9 and I have a question about the guide and can’t find the answer. (I can’t find it in the guide itself).
At the moveslist of the characters, there are notes:

Red, blue en green ones.
In general, what do the different colours mean?

In detail:
Red:
High/Mid/Low:I think this is where the attack connects and how you need to block it??
Unblockable: can’t you do anything against this?
Throw: it throws :slight_smile:
Blue:
Ground bounce: ?
Knockdown: This moves knocks down you opponent?
Sweep: it sweeps (don’t know how to explain this)
Flatten: ?
Launch: ?
OTG: ?
Stagger: ?
Green:
Bufferable: ?
AIROK: ?

PS: Shouldn’t this be explained in the guide itself?

Thx a lot
