Some people have color synesthesia: they experience various patterns as colors. For example, in number-color synesthesia, the person experiences numbers as having colors regardless of their literal visual color. For example, the numeral 7 might appear as a particular shade of green. Some of these color synesthetes are color blind due to genetic defects in their light detectors. Nonetheless they appear to experience the full range of synesthesic colors including ones they have never seen by direct perception. One person called them Martian colors.
