Yeah I know. I can’t even picture their flag without red white and blue. The first two are the only one’s I find tolerable.

In the old days, you could combine the symbols of the remaining countries into a flag like the royal standard (which still flies over royal residences when the monarch is present):

That's probably one thing you can't easily do today. The preference is for more abstract geometric designs, like the existing UK flag. Curiously, the Scots got a variant of the royal standard with two Scots quadrants rather than two English.
