Oh interesting - is this in any way related to why the Israel flag went with blue?

Also, the two lines in the flag are tzitzit (cords) which are supposed to be blue. https://en.wikipedia.org/wiki/Tzitzit

Yep, that and a bunch of ancient Jewish texts mention using blue within religious contexts with spiritual meaning. It's come to be that blue has been considered by Jews as a color that is representative of the Jewish people
