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). 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 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? 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).
