One thing I noticed as someone with red-green colour blindness is that while the article claims that "darker magentas are more distinguishable than lighter ones", I saw lighter magentas as being more distinguishable than darker ones. So the perceptual distances between colours are probably different for us.
If high contrast between colours is desired, you could take some further precautions in some of the suggested algorithms, e.g. if you're choosing certain hues as a basis of your palette, then making sure that none of the pairs are problematic. If your algorithm checks the distance between colours to generate high-contrast pairs, then you could add in a check for problematic pairs as part of that step.

How do you know you are looking to equivalent distributions of lighter and darker magentas? I have some uncommon kind of color blindness, I have problems with blue and green. I don't even know what colors I can't see, I'd love to know the procedures for that.
- Jongseong 13y agoI was looking at the sample image provided on the linked article for hue differentiation where for each of the three rows, the strips of colour differ by 5%. The three rows differ by brightness only. The article used this image to illustrate that "lighter blues is more distinguishable than darker blues, while darker magentas are more distinguishable than lighter ones", but to me both lighter blues and lighter magentas were more distinguishable than the darker counterparts.
