So, according to the palette guide in the game, the LP+MK+HP colors are part of the default colors. However, whenever I press the buttons for this color, I get the HK color instead. I tried it for the 2nd Impact palette as well for the same problem. Apparently beating the game with the character you want that palette for doesn’t help, either.
Are you using a stick where the button layout is different than standard? I think the game needs you to select these costumes with X + B + RB on Xbox and squarre + X + R1 on PS3 until you set your buttons or w/e. Some shit like that. You’re getting the HK color because if you select your character with multiple buttons, other than the pre-assigned three button color, you get HK.
Remember that the game doesn’t swap the default controls in the character select screen if you remap your buttons. That is, X is still LP and R2 is still HK, and so forth. It’s stupid, but just needs some getting used to. Obviously, if you stick has some kind of ghetto button layout, it’s going to cause more issues.
It works, it just depends on which way your buttons are mapped. For me, the seventh color works with LowPunch+MediumKick+HighKick (not HighPunch as you’d expect). It’s stupid.
