Hi, my name is Chris Campbell and I have a color vision deficiency. Like roughly 7-10% of all males, my deuteranomaly makes it difficult to differentiate between some colors, like red and green. Color deficiency, or color blindness as it’s commonly referred to, doesn’t mean that I or people with similar conditions cannot see certain colors. They’re not invisible and I don’t see in black and white (a condition that is actually very, very rare). I can still use crayons effectively, find meaning in beautiful sunsets and even enjoy clear blue skies. What it does mean is that certain colors in the visual spectrum look a lot like one another and so I have a hard time sometimes telling the difference between certain colors and even shades.
Title says it all: Chris Campbell gives very good examples and ways to deal with colour blindness.
