16personalities
A website that offers personality tests based on the Myers-Briggs Type Indicator model.
They have color-coded designs for every personality type, which are then often used as bases for character creation by artists.
If a character based on an MBTI type doesn't take cues or inspiration from these designs, original would be better suited.
