what we'd expect to see, at the price of accurate reproduction

Can you explain what this means. Since our eyes are the only reference we have for interpreting colors (the other being wavelength, and that's just a number) I'm curious what an accurate color really means. I know that we can see billions of colors but only a thousands at the same time.



I'm referring to the star chart, not the colors. You'll notice the curvy artifacts in the chart that looks like the ones found at this link:

Those curves are an illusion. They don't actually appear in the image. We see them because of the tiny, staggered parallel lines required to reproduce an angled line using a grid pixel array. You can optimize to reduce this effect by using different anti-aliasing techniques that are specific to the type of display you're using. Apple tends to favor "soft" anti-aliasing techniques over accuracy. They also have the benefit of controlling the entire software stack, so their image processing can optimize for the IPS display used in iOS devices.

Some people find the softness downright obnoxious, while others think it results in the most pleasing image. I prefer Apple's method.

Color perception is a very broad topic. It's one of those "why is the sky blue" questions that we've all pondered (and frequently arrive at a false conclusion). I'm not nearly knowledgable enough to talk about it with authority, but you should definitely do some Googling, and be sure to keep an open mind. The answer is probably not what you think.
