The navy found that the sky blue washed out too quickly, so they began using a darker blue, and eventually that became standard.
It comes from the colour of the uniforms worn by British naval officers, but they wore that particular colour because it matched the Jack, so I guess it amounts to the same thing.Is this where the term "navy blue" comes from then?
So what's with the red X and the white cross in the UK's flag? Just thought it looked nicer than a red cross on a white X alone?
In theory, although there's scarce record of the St. Patrick's satire being used as an Irish symbol before 1800, so I'd say that the addition is partly aesthetic.It's because of Ireland
