Exports a Dict of Colorschemes, representing the colors found in (almost?)
all flags from the database at
flagpedia.net.
These colorschemes were automatically created, and no part of this package is in any way intended as a political statement. Any errors are likely to be due to quirks in parsing the svg files. Specifically, some flags are entirely white. This is not a play on the surrender flag, but my parsing function returning white as a default when the svg specifies some exotic color format. Please submit a PR to correct any such deviations found.
The colorschemes are meant to be used to represent different countries in data vizualisations, but are not guaranteed to be effective for this purpose. The colors are likely to be similar, non-print-safe, and don't necessarily represent the order or relative abundance of the colors in the respective flag. Always check your visualizations against visualization guidelines before publication.
The colorschemes are accessed through indexing into the flagcolors dictionary
with the ISO3166 two-letter code as a Symbol (in some cases it's a bit more
complicated, see the Texas example below). If you don't know your country's
ISO3166 code, your top web domain is a good guess.

plot(rand(5,5),color=flagcolors[:us][1]) # Extract the red from the US flag
plot(rand(5),st=:scatter,marker_z=range(0,1,length=5),color_z=cgrad(flagcolors[:se])) # Use the Swedish flag as a color gradient
plot(rand(5),color=flagcolors[Symbol("us-tx")][0.5]) # Use the color in the middle of the colorscheme for the Texas flag. Note: some names need to be given like this because they contain non-symbol characters like '-'
