Bleu myosotis (“Forget-me-not” blue): named after the flower of that very same name. Based on the famous legend, a knight and his lady were taking a walk along the river. He bent over to pick up a flower for his lady but lost his balance with the weight of its armor and fell into the river. While drowning he threw the flower at his lady screaming “Forget-me-not”.
Thanks to that legend the myosotis had become the symbol of memory and remembrance. The bleu myosotis is also the closest color to the standard and traditional blue ink used by every French pupil.
