There is no background color. The surface that you apply the sticker to will become your background color. This is a DIE-CUT vinyl decal meaning that the background has been trimmed off. If there is a background color in the picture, it is used only as a representation. The background color will be the surface color you place the sticker on (or clear if you put it on a window). The decal will come with clear transfer tape, so you can easily apply it to anything you like (walls, windows, cars, mailbox, mirrors, laptops, etc etc etc). We use High quality Oracal 651 brand vinyl for all decals. Application is relatively easy. Some decals are more difficult to apply than others (especially the little ones!) - likewise, some surfaces are more difficult to apply decals to.
