The Castle is where we are, so I was thinking that should be primary.
Turquoise is blue...there are many shades of blue, but in designing an enSIGN, (RAC...) we need to make sure our purpose is suggested.
Blue, in this case (almost any shade) is a neutral color.
Of course, if need be, there can be one flag with the castle on it, then below that, a pennant for each of the habitats.
That would prevent the main standard from being too busy, while still allowing the habitats to state their “claim to fame” as it were.
We might also want to consider a pennant for the bridge, as well.
But, but, but....
What happens when the Navy blew porpoise is actually promoted instead of just being suggested?
