Colors

[Searcher]

I think the blue and green in quire 13 is intentionally placed, and that they indicate fresh and saltwater respectively. There are many places where the two are mixed, or where different pools are coloured blue and green on the same page. I can think of no reason to do this if the two colours were considered equal.

I think all the biggest pools were colored first, some/long time before the author get blue pigment, therefore they are green. But this is only my opinion.
