Fun fact: Disney/Pixar officially registered the DunBroch family tartan with the Scottish Registry of Tartans on June 22 2012. The registration notes detail the reasoning behind the look of the tartan.
“Much like Scotland itself, the DunBroch Tartan is set against the ocean blue of the North Sea. The deep scarlet represents the family’s reverence for its own history, and the blood shed during battles between the clans. Deep green shows a love for Scotland’s majestic highlands, where the story of Disney Pixar’s ‘Brave’ unfolds. Navy blue, and its clear central intersections, represents the forging of the clans within the DunBroch kingdom. And finally, the subtle grey imbues a sense of respect for the inner soul of the strong Scottish people.”
