How to change the outfit color?

I am trying to use the swap shop ítems for get an outfit color change token,but no way,i can not change ítems and i have a lot. Any help should be wonderful.

Okay, so are you having problems getting the Color Change Pass from the Swap Shop, or are you asking how to change the outfit color?

If it is the first, make sure that the items you are using have the green AC-item icon on them (example) and are not locked or equipped.

If it is the latter, then you do so in the Salon, and you can only change the colors of Outerwear, single-piece Outfits with the Color icon (example), and CAST colors; Basewear, Innerwear, and fixed-color single-piece Outfits (ie. those without the Color icon) cannot have their color changed.
