Pirate flags are black and white. The coin is grey and white. Where do the colors come from?
I could get on board with "Hoist the flag"
The shirt is great otherwise, though.
A ship's flag was often called "her colors", as from at a distance, colors was all that could be seen. so running a flag up the mast was called hoisting the colors.
And you've spelt colours wrong too
Well shit
Tickle me crow's nest - What's wrong with "Hoist the Jolly Roger!"?
It's technically what Pirate flags are called and were hoisted before going into combat.
If on the other hand, we're pacifistic pirates then colors will do just fine.
