Sanguine

Red chalk

Red chalk is chalk of a reddish-brown color, which was used as a material for drawing. It is obtained from the red ochre variety of hematite. Another term for red chalk, common in older references, is sanguine. The word comes via French from the Italian sanguigna and is originally from the Latin "sanguis"; it refers to the color's similarity to that of dried blood.

Four temperaments

The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic. Most formulations include the possibility of mixtures among the types where an individual's personality types overlap and they share two or more temperaments. Greek physician Hippocrates described the four temperaments as part of the ancient medical concept of humourism, which states that four bodily fluids affect human personality traits and behaviours. Modern medical science does not define a fixed relationship between internal secretions and personality, although some psychological personality type systems use categories similar to the Greek temperaments.
