>For instance, in the following HSL color scale the brightness step between the second and the third red appears much bigger than the step between the 3th and 4th color. Even worse, this effect seems to differ across different hues, as the comparison to the blue scale shows. I honestly can't see what they're talking about in the example images. Is this a "some people are more visually sensitive than others" type thing, or is this the visual equivalent of audiophiles messing about with bespoke setups to try and get marginal improvements in sound quality?

The former; I would guess most people can see the difference. If not most, then still a very large number, more than the statistically insignificant number that would be able to differentiate gold plated cables or whatever.

The difference should be readily visible. Various aspects of visual sensitivity can certainly vary between people but I think it's far more likely that your monitor isn't very well calibrated or is possibly just of low quality. In my case, the difference is barely visible on the profile I typically have loaded because I modified it to maximize brightness and text legibility at the expense of significant color accuracy.

  I think the claim that the difference in the first pair was much bigger was probably overstated. Would I say the difference appeared bigger in that case? Yes. But on a calibrated screen, as someone with no known colour vision deficiencies, and as someone who does a lot of design work including fine-tuning colour schemes, there is a clear step between each adjacent pair of reds on that scale to me, and the perceived differences between the steps aren't that big. If I had to guess, I'd suggest that some people see the second red darker than it should be due to poor colour reproduction on their monitor, which would exaggerate the difference from second to third red.

I was curious if the surrounding colours influenced things so I cut out just the two pairs and presented them on a white screen. The first progression definitely looks like a bigger change to me like they said. Putting it on a black background seemed to reduce the effect, but the same pairing still won.

This is a recurring problem for me. I work as a graphics programmer and many papers in the field employ comparison screenshots to show the difference between techniques. Since I have a moderate case of colour blindness,I often can't tell the difference.
