If you are entering your hex color by hand make sure to add "0xFFFFFF" instead of just "FFFFFF". On our new release of our site tomorrow, there will be a different way to enter the color where you will not need the "0x------". Also, you will have the option to pick any "Auctiva Template" and have a matching store window that goes with it! Hope that helps, if not let me know exactly what you are entering when it gives you the undesired results.
