I got your point, tnx for sharing this YouTube channel.
lets wait for the new GoPro 🤞
btw Now I understand my idea of blue, in the past few summers I dove in aeolian and pelagean islands,😀
I found with my eyes a nice blue also in ustica but later I had to work a lot with CC, due to’ predominant green in some dive site.
I dive usually in Tuscany and Liguria,
sometimes I can find green but sometimes I can find blue hue.
For blue or green in the med I think also it depend on how is the light at that time and the current flow in the last 24hr.
i would like to get more knowledge on this topic.
