Tomorrow Scotland will hold a historic vote on whether to break away from the United Kingdom or not. Never mind the social, political, economic ramifications of secession—if the Scots bail out, there will be a bit of a graphic design problem to address.

That's because the Union Jack, the flag of the United Kingdom, is in fact a 19th-Century mashup of three different flags: The English's St. George's Cross blazon...

...Northern Ireland's Saint Patrick's Saltire (a "saltire" being a diagonal cross)...

...and Scotland's Saint Andrew's Cross, which is technically a saltire.

Put them all together, and you've got three great tastes that (perhaps used to) taste great together:

You'll notice that the flag of Wales, which is also of course under the UK umbrella, is not included in the Union Jack. Presumably because it's not an easy ingredient to mash up:

That doesn't provide a full excuse as to why Wales hasn't been included, as they do also have the flag of Saint David (Patron Saint of Wales) which is more graphically consistent with the rest:

So what happens if Scotland breaks away? The most obvious choice, as now being presented in British newspapers like The Daily Mail and The Guardian, is to simply ditch the Saint Andrew blue:

Another line of thinking goes that it's time to cut Wales in on the deal, but maybe lose the dragon:

For those not feeling the green, there's also the option to go with a half-assed mash-up with the Saint David that loses the yellow:

Or to give in and go with the yellow:

Of course, maybe Scotland will vote to remain in the union, and it will be a moot point (aside from whatever ill feelings Welshmen might harbor). But one thing seems for sure: If Scotland votes "We're outta here," the blue is most certainly gone. According to The Guardian,

[Should Scotland vote for independence] Lord West, the deputy chairman of the parliamentary flags and heraldry committee, suggested last week that it was "nonsense" to imagine the St Andrew's blue could remain.
