More than likely, no. Most BPs have something of an 'iridescent sheen'. It's actually most noticeable AFTER they have shed. Here's some tell-tale signs to look for though, to help you in the future:

1. A pink belly - just like it says, their underside will become noticeably pinker.
2. Skin wrinkles.
3. And last, but not least, the blue stage.

If you haven't heard already, the eyes will fade back to normal just a day or two before the actual shed.

Once you become more in tune with your BP, it will take just a glance to know when they're in shed.
