It might have always been the case, but now, definitively, Lulu is using CMYK mode, which means, if you created your cover in RGB mode the colors will change. And if you try to switch modes in the middle of cover creation (in Photoshop), it will flatten all your layers. So, you basically have to start in CMYK. If it's too late, just save an RGB mode backup file with the layers before you switch.
Winter should be able to fill everyone in on the details.
