This is of course why we measure proofs. Customers can generally accept that everyone's vision may be slightly different and that a measurement can be accepted as a consistent representation of "average" vision. That together with an accurate proofing system (with verification ticket attached or printed on the proof) and carefully chosen reference profile greatly minimizes the anxiety caused by the knowledge that we don't all see exactly the same way. Frankly, in practice other factors are far more troublesome, including failure to simulate color of actual production substrates and inconsistent inclusion/exclusion of UV in measurements. These cause mismatches that EVERYONE sees.

By the time you're toasty enough to roll over, the resulting chromatic adaptation will be a *lot* more than the 800K difference the author of the article describes.

But the closed / shaded eye thing was something I discovered as a young child, and it remains by far the most dramatic example I've ever come across.
