No they arent

Wow apple, great job!

I hope this is a joke

Yes. Pretty common among men, a trait from their mothers as it lies on the X chromosome. Most women dont have it, as they have a healthy one and it is recessive.

I work with industrial human machine interfaces, used to operate heavy machinery. The prevalence of some form of colorblindness in the male population is around 15-17%, and most heavy machine operators are men.

It’s enough of a safety issue that standards call for at least 2 ways of communicating alarms - most commonly shapes and colors, in many cases text is also used. The use of colors to indicate status (pump running, valve closed, etc) is also limited to colors with a distinct luminance value so that even people with full colorblindness can operate them easily.

In the past, many HMIs were made in which green meant running, red stopped, yellow alarm… let’s just say a lot of people had to be maimed and killed before the standard was issued.

You're right, a keyboard-driven tiling wm does seem like a better idea.
