Solid Color on iPod/iPhone home screen for low vision users?

Low Vision Accessibility on Apple Products
First of all, is there a "native" way to make the wallpaper be a solid color (as opposed to an image) on your iPod/iPhone home screen? If not, I see that there are a few apps out there that can do this. Does anyone know if any of these apps are accessible with VoiceOver (in the sense that at least the controls are accessible, not necessarily the color descriptions or anything)?
