Notes on most common colours

Since there is huge variety in the colours of the national flags, it makes sense to "round" each pixel to the "nearest" of a selection of common colours (measured by Euclidean distance). Otherwise, we would have 1000s of colours, most of them with negligible frequency. The common colours used were: white, silver, gray, black, red, maroon, yellow, olive, lime, green, aqua, teal, blue, navy, fuchsia and purple. We see that red is the most common colour in national flags; the colour of passion, excitement, danger, and McDonald's.

You can’t perform that action at this time.
