When the display vendor advertises 1 billion colors, a knowledgeable reader
takes that as "supports 10-bit per channel data" and connects this to the
value of the 2 extra bits for emerging performance standards and evolving
formats.
But sure, my fav example is Photoshop Lab has like poor coding efficiency,
so 1/3 of the values available correspond to no idea of color whatsoever!
Compared to sRGB or CMYK it has like 30% efficiency and designers used to
dump their data into Lab to perform a quick chop not realizing they'd put
their image through a colander. But as you rightly note, you can get away
with very few bits if they're properly perceptual distributed. Isn't this
the beautiful thing about all compression modes?
If you understand the model and the coding, you don't fret about it, unless
you see it being misused, you just understand the limits of the tool.
So I am not hung up about the word color in context.
I do share your sense that marketing could do a better job of helping built
understanding. But for a full generation, marketing was as much about
bullshitting that a competitors claims don't matter as it was about
communication. The distinction between teaching and persuading.
Why does marketing it have to be so obtuse? I've tried writing ad copy and
it's hard. I began to see that almost all simple speech is lying
because it's so context dependent. And who are "you" to decide the
conventions of thought? IOW, act freely but do so at your own peril :)
There was this little company called Apple Computers back in the day, they
they invented something cool and for Ridley Scott to design a compelling ad
about how their main competitor was like a "big brother" telling all the
thralls what to do. Later after a lot of success, they invoked Einstein and
Picaso as their mascots. Think Different they said. Now they are like the
Borg andtheir leaders moved to a big donut shaped spaceship and seem not to
care about anything but themselves. C'est la v... Something.
I do share your sense of the danger of a culture that traffics deeply in
BS, And I worry more about since the internet let me meet "fan culture,"
and now I am stunned into amazement at how baby Yoda is as significant a
popular concern.
But the term "color" in "1 billion colors" context seems pretty innocent.
