Shifting perspective: why my shirt is red
I am colour blind. No, it doesn't mean I see the world in black and white. Yes, it does mean that my red t-shirt to you might be olive green to me. The reality is that the colours I perceive are different from what most people see.
Colour blindness : beyond the disease, another perception of colours
Colour blindness is not a disease, but a genetic condition that affects the way I perceive colours. It is something I have always known and it is part of me.
John Dalton : the science behind the anomaly
The term "colour blindness" comes from John Dalton, an 18th century British scientist, who was the first to study this condition after realising that he himself was colour blind.
Understanding colours : the importance of cones
Colour blindness is a condition that affects the cones, the cells in our eyes that detect colours. Due to a genetic mutation, some of my cones don't work as they should, which alters my perception of colours.
There are several types of colour blindness, including protanopia and deuteranopia, which affect the perception of red and green, respectively. In my case, I am protanopic.
The Genetic Mechanisms of Color Blindness
Behind the scenes of genetics: why am I colour blind?
Colour blindness is usually inherited and is caused by a mutation on the X chromosome. Because males have only one X chromosome, they are more likely to have this condition.
Discovering colour blindness: my personal experience
The moment I knew : how I discovered my colour blindness
I discovered my colour blindness at the age of eight, when I had difficulty distinguishing colours in a colour vision test at school.
Seeing the world through my eyes : the vision of a colour-blind man
Colour blind people, like me, do not see the world without colour. On the contrary, we perceive colours differently. For example, I might mistake red for brown or green for yellow.
Living colour-blind: challenges and common myths
No, I'm not a freak : breaking down stereotypes about colour blindness
Being colour blind does not make me "abnormal". It is simply a quirk that affects the way I see the world. I would like people to understand that colour blindness is not a disability, but simply a different way of perceiving colours.
No, red is not green : understanding the lack of understanding
Yes, sometimes I confuse red and green. No, that doesn't mean I see red as green. It's more complex than that and varies from colour blind to colour blind.
How I see the world
Seeing the world as a colour blind person is like looking at an alternative version of reality. It is a unique experience that has taught me to appreciate differences and to understand that everyone has their own unique perspective. And it is beautiful.
