The term âblue bloodâ means a person of noble birth. It is an idiomatic expression that originated in Spain, referring to the paleness of aristocrats who had never married into Moorish or Jewish families. In medieval Europe the nobility did not work for a living, and so remained untanned by the sun and wind of the fields.
