    Ok, I obviously haven't seen the aforementioned cig paper. Nevertheless, our eyes are less sensitive to blue than green, so blue will appear darker! I suppose there could be individual variation in the perception, as Vsauce talk about in this video:

    The Greeks imported indigo dye from India, calling it indikon. They used Egyptian blue in the wall paintings of Knossos, in Crete, (2100 BC). It was not one of the four primary colours for Greek painting described by Pliny the Elder (red, yellow, black and white), but nonetheless it was used as a background colour behind the friezes on Greek temples and to colour the beards of Greek statues.[15]

    The Romans also imported indigo dye, but blue was the colour of working class clothing; the nobles and rich wore white, black, red or violet. Blue was considered the colour of mourning. It was also considered the colour of barbarians; Julius Caesar reported that the Celts and Germans dyed their faces blue to frighten their enemies, and tinted their hair blue when they grew old.[16]

    But they did use blue dye in the Med area, extracted from a local sea snail:

    yes.

    Btw I can't find the source where it was said that Vikings hated the color blue. I searched for it and couldn't find it.

    This video tries to explain the whole issue:
    The husband who decides to surprise his wife is often very much surprised himself.

    This is interesting since the color blue has the most shades to the human eye.

    Don't let the flag confuse you, this video is about colours. It explains some shit about purple and violet, the former looks like the latter, but the latter doesn't actually exist. the end of blue on a spectrum is violet, but do we actually see that colour, or...

    Further explanation (Magentha, which is basically a kind of purple)

    (there's even an interesting discussion below the video, which is a rare phenomenon on YT)
