Everyone sees and experiences the world differently from you.
And you need to remember this when creating something. Other people will not see things exactly as you do, or as you want them to.
I recently came across a fantastic example of this, which also happens to be a wonderful innovation.
It’s a pair of special glasses created by a company called Enchroma, which enables people with colour blindness to see the world like everyone without colour blindness do. The video above shows someone with colour blindness putting them on for the first time, and seeing colours they have never experienced before.
This resulted in the wonderful phrase he says:
Is this purple?
Over 300 million people, or 4.3% of the world’s population, suffer from colour blindness. The reason for this is that the cells in their retina pick up a broader spectrum of light than they should, which makes each wavelength of light produce a less distinct signal. So several shades of colours become merged together. The enchroma technology explanation below gives you an indication as to what effect this has on the experience of a colourblind person.
