The Supreme Court has directed the Film and Television Institute of India (FTII) not to exclude candidates suffering from colour blindness from its courses on film making and editing and asked it to make changes to its curriculum instead.  The court agreed with the conclusion of an expert committee that the colour grading module of the editing course has “no relevance or nexus with the role of a film editor”.

What is colour blindness?

  1. Colour blindness, also known as colour deficiency, is the inability to see colours in the normal way.
  2. Colour blind individuals often cannot distinguish between certain colours — usually greens and reds, and sometimes blues as well.
  3. Two types of cells in the retina detect light — the “rods”, which distinguish between light and dark, and the “cones” that detect colour.
  4. There are three types of cones that see colour — red, green, and blue — and our brains use the information from these cells to perceive colour.
  5. Colour blindness can be the result of the absence of one or more of these cone cells, or their failure to work properly.
  6. In a situation where all three cone cells are present but one of them is malfunctioning, mild colour blindness may occur.
  7. Colour blindness may be of different kinds and degrees. Mildly colour blind people often see all colours properly only when the light is good; there are others who cannot tell one colour apart from another no matter how good the light is.
  8. In the most severe kind of colour blindness, vision is black-and-white, that is, everything appears as a shade of grey. This is not very common.
