70c

Did a spot of beachcoming for seaglass today, and these are the most interesting pieces I found. The blue wins it though. Very unusual shade (at least within my experience).

It does make the process interesting when the tide is right in and the wind is up and so you're grabbing a piece and then having to take two very hasty steps backwards to avoid getting your feet soaked. ('Semi-Extreme Beachcoming' perhaps?)
