Et meeerrdee,

J'ai une nouvelle déformation de la macula 😭

Elle est gênante. C'est une nouvelle zone "morte" dans mon champ de vision, la lecture va encore en patir, sans parler du reste

Vais aller pleurer 🤧

#PhysicsFactlet
The human eyes have "only" 3 different colour receptors, so multiple spectra can be perceived as the same colour.
(And this without considering all the ways the signal is processed before you actually "see" it.)

On the left, the absorption spectra of the 3 human colour receptors, with a varying spectrum (shown as a black line) on top. On the right a disk coloured with the RGB equivalent of that spectrum.

Before designing a website, or even making a small change to an existing one, ask if your design choices consider the needs of people with color blindness. Changing the button color on your website may seem insignificant, but it could make that website inaccessible to nearly 8% of men and 0.4% of women who have color blindness.
