You may recall a recent visit to your hairdressing salon. While you sit in the reception area waiting for your appointment, either reading a book or leafing through a magazine, you watch as each stylist cuts a client’s hair, finishes a setting, or works on a someone’s hair colour. Each of these activities requires specific lighting needs: a hair stylist needs proper lighting to cut a client’s hair with precision, or to select the appropriate hair dye colour. Clients must be able to consult hair styling magazines, decide on the cut that is most suitable, and pick out a hair colour they like and enjoy the end result. Three specific lighting elements are required in this scenario: the illumination level, colour rendering and colour temperature.
