NOTE: Neil Harbisson

https://en.wikipedia.org/wiki/Neil_Harbisson

Harbisson was born with achromatopsia, an extreme form of colour blindness, which only allows him to see in grayscale.

A person with complete achromatopsia see only black, white and shades of grey. The image is blurry in bright light and sharper at low lighting levels.

Harbisson's antenna, which has been permanently attached to his head since 2004, is osseointegrated inside his skull and sprouts from within his occipital bone. It allows him to hear the light frequencies of the spectrum including invisible colours such as infrareds and ultra violets. Internal internet connection also allows him to receive colors from satellites and other people's cameras, as well as receive phone calls directly into his skull.

The antenna consists of 4 different implants: two antenna implants, one vibration/sound implant, and a Bluetooth implant that allows him to connect to the internet.
