The Blue-Yellow Blur (Tritanopia)

The Daily Struggle: Losing the Sky and Sea:

Tritanopia Is the "rare bird" of colorblindness. It affects the short-wavelength (blue) cones. While red-green colorblindness is about "warm" colors, Tritans struggle with the "cool" side of the wheel. Blue looks green, and yellow looks violet or grey. In the wardrobe, this means "Navy vs. Black" isn't the problem—the problem is "Pink vs. Yellow" or "Purple vs. Red." It’s a confusing landscape where a bright summer outfit can look completely different to the wearer than it does to the world.

The Genetics: The Equal Opportunity Mutation Unlike the other two, Tritanopia is Autosomal Dominant.

• Not on the X: The gene is located on Chromosome 7, which isn't a sex chromosome.

• Equal Odds: It affects men and women at the same rate.

• The Flip: Because it’s dominant, you only need one parent to pass it down to potentially inherit it. However, many cases of Tritanopia are actually acquired later in life due to aging or medical conditions, rather than just birth.
