Default Will clear iodine work for the starch test?

Wondering if the clear, decolorized iodine will work for the starch / full conversion test. My guess is it will if it is the iodine that changes colour and not the colour added to the iodine that changes. My guess is if there is no starch left the clear iodine will stay clear, otherwise it will turn purple. Any thoughts?

If you have some try it with some bread crumbs and see. I have never heard of clear iodine. Cool stuff if it works
