where this color comes from
The flag of the United Kingdom, the Union Jack, layers red and white crosses over a blue field.

It's the shade of the drawing used in the game, not an official color.
This red is fairly dark and slightly pinkish. In the game, it has exactly the same code as the red of the Danish and Austrian flags (#C8102E, a ΔE gap of 0). It is close to the red of the Japanese flag (#BC002D, ΔE of 3.2). Surrounded by dark blue and white, this red looks brighter than it is, and many players choose it too light. In the big square, aim for pure red, slide very slightly toward pink, then make it slightly darker than medium.
