Also, obvious option is obvious, but must be mentioned: if the colors are being saved after the defaults instead of amongst them, make sure you're scrolling to the right if it's available. Or you can go and look for recolored cc by the hair name. Look into Sims 4 Studio, make sure you’re downloading the right one, get an easy art program like GIMP, and you’ll be okay. When you say, 'when I come back it will be gone,' what precisely do you mean by 'come back'? Switching to a different color, then wanting to go back? Leaving Create-A-Sim and then re-entering to make a new sim? Exiting the game entirely, and coming back a day or so later? Is this only when you're in Create-A-Sim at the start of a game? When you're using the Salon in game? A mirror or a dresser? When you click on the 'save to bin' option, are you getting the little pop up window? If it's unique, it will say it's saved, but if there's an existing color, it'll tell you so too (I say this only because I know far too many people who are notorious for not reading the messages). Luckily retextures and coloring is actually pretty easy once you get the hang of it. Then you can follow the instructions here to upload. Screen shots would be to hit 'print screen' if you're on a PC (Mac method is escaping my memory at the moment).
