Chelsea Smith and Tirta Susilo published their work showing that Developmental Prosopagnosia is not linked to colour perception deficits.

Developmental prosopagnosia (DP) is a selective neurodevelopmental condition defined by lifelong impairments in face recognition.

Individuals with DP suffer from lifelong face-recognition deficits, despite having normal low-level vision and general intelligence. Despite much research, the extent to which DP is associated with broader visual deficits beyond face processing is unclear.

Group-level analysis shows comparable performance between DP and control individuals across colour perception tests, and single-case analyses indicate that the prevalence of colour deficits is low and comparable to that in the general population. This study demonstrates that facial recognition deficits in DP are not associated with broader visual deficits in colour perception.
