blue starch: Part 2

My recent analysis of starch residues on stone tools from the Sannai-Maruyama site will be done soon. During this analysis, I found more blue starch granules than those in my 2006's survey.

Today I found the following blue starch granule with a blue plant tissue. I really want to know about the reason.
