Why are the colors red, white, and blue used in the Union Jack design?
The Union Jack design isn’t just a random mix of red, white, and blue — it’s a layered symbol of political history.
These colors come from combining three distinct flags:
Red on White – St. George’s Cross (England)
White on Blue – St. Andrew’s Cross (Scotland)
Red on White Diagonal – St. Patrick’s Cross (Ireland)
When these were merged, the result was the Union Jack — a single design representing the union of different nations under one flag. The colors weren’t chosen for abstract meanings like bravery or loyalty, but to preserve the visual elements of each individual cross.
It’s a fascinating example of how design can carry centuries of history in a simple pattern.
