Percival Day Two

The blood on the snow reminds Percival of Blancheflor because it's a symbol of his red armor and the white snow, the two colors of these characters. And While I'm more used to white and black being compatible such as in bleach, this might not be the case in western mythology. Whit is pure, red is blood. Perhaps this is to remind Percival of her, her weeping over him as he sleeps because he can't understand the world she's coming from. Red can certainly let us think that Percival is at first just out for the glory of it all, ridding around with no idea what he's doing at all. And this true when he stabs the Red Knight through the left eye after he had been knocked from his horse. But as we move along he becomes... better at deciding what to do, and how a night should act. Perhaps the blood in the snow is just another reminder.
