Rubik's cube color majority riddle

Max and Feliks are playing a game. Max scrumbles the Rubik's cube (3x3) and pick a color that Feliks needs to make a side with a majority of the color that Max chose. considering that Feliks is making perfect and most efficient moves what is the maximum moves that Feilks will have to do in the worst case scenario. sorry for my English. some deeper explanation if this wasn't clear enough, a majority of a color means five or more, two moves at the same direction count as one.
