Lucy Engelman has synesthesia, which is a perceptual response where one sensory pathway is stimulated, and a secondary sense is triggered. Daniel Mullen, in collaboration with Engelman, paints what she sees through the secondary sense.
In Lucy’s case, when she sees or thinks about time and numbers (days of the week, months, hours, years) as well as letters/words ie a person’s name, she experiences a different colour sequence in her mind’s eye. Additionally, time is spatial and coloured related, as in the days of the week, months, years, all have a coloured location in space and a shifting orientation. Essentially, she has an ever changing complex and luminous filter to view the abstract concepts of our world.
