    Probably related to dark winters, cloudy weather, low melanin levels, and genetic isolation on islands.

    I’m just guessing the following:

    Trade and shipping from the British isles across the North Sea to the Baltics also moved people along those routes.

    The red center in Russia might be due to Viking settlement and establishment of Rus.

    Blond and blue eyes have a high distribution around the Baltic Sea mostly due to similar reasons.
