Hi Andrew, would you be so kind as to contextualize your observations?
Why is it significant that there might be indistinguishable colors in an 8
bpc format vs an 10 bpc format?
Aren't Indistinguishable colors a trivial concern? Just turn off your
screen and bamm! :)
The marketeers have "counted" the "colors". It's as simple as this. And the
claim is no lie🎱
If you're gonna trudge on about invisible colors, we should keep in mind
that as well as color blindness, which is quite common 1/13 men I think,
there are some people—very rare and typically women—who can see well beyond
the spectrum locus, like they can see a fourth primary. Also, from an
anthropological perspective, local populations have been found that can
distinguish within certain ranges, say green, much better than average.
Then there is the psychological adaptation: you can learn to observe.
And there's the matter of unconscious bias, as this whole topic of the
physics of the qualia is being encountered under the even more strange and
elusive regime of language.
It seems like what you are saying is the "billions of colors" claim is a
spooky bit of both?
If you don't need 10 bpc that's fine.
Per Florian's comment about cal headroom, and Roger's question about HW
LUTs, putting the extra bits in the display can add life to good 'ol 24bit
color systems.
If what you are saying is a high fidelity image can be built from a small
palette, isn't that called half-toning? Aren't you DTP nerds?! omg2
