Hello,

The RGB color space does not contain/display all colors we humans see in
reality...

In reality we humans see more colors in real-life than our monitors can
display.

I was wondering if nvidia is researching graphics cards and/or monitor which
try to display "realistic colors" ?!?

If not it would seem to me that "they" have the most to gain from such
technology and should therefore research/develop it ?!?! ;) :)

Might be the next big thing or maybe not...

I do wonder what "changes" would be needed to the current system...

How many bits would be necessary to display all colors ? Would it still be
an RGB system or would it need something else ? ;)

I can vagely remember one company investigating such technology and working
together with some animation studio... like pixar ? or industrial light and
magic ?

Bye,
Skybuck.

In reality our monitors can output more colors than our eyes can process.

Maybe it's not about "number of colors" but the "color range" itself.

Like deep black, and very white.

And very red and very blue, and very pink, very orange and so forth.

Monitors seem to be limited to a certain color range.

For that you would need monitors with an infinite number of primaries.
As (most) monitors and the color system of the computer-monitor
connection (say VGA and DVI) are based on three primaries, all colors
that can be reproduced by a monitor are contained in a triangle in the
xy color space whose edges are given by the (phyiscal) colors of the
monitor (inside the full gammut). However, the gammut of visible colors
in this space is certainly *not* triangular, thus necessarily colors are
missing.

It is not a matter of the monitor or the graphics card, but the whole
system to signal colors.

Not a matter of bit-count (alone). The bit-count only defines the
precision by which colors can be represented, not the size of the gammut.

OpenEXR, by ILM. But this is on high-dynamic range images, i.e.
representing several magnitudes of luminance. But it is still based on
three primaries, and so are (most) capture devices and (most) display
devices. IIRC, the primaries can be specified, thus it is possible to
describe "virtual" colors outside of the visible gammut and thus
describe all visible colors. However, since the monitor and the
monitor-computer link is constrained to "physical" colors, that itself
doesn't buy you much; it is a win for processing images - i.e. in the
image or movie processing toolchain, because coding loss can be avoided.
This is what it has been designed for.

Greetings,
Thomas

I have seen drawings trying to explain it... the "true" gammut seems a bit
wobbly...

Maybe a (cubic?) spline system is needed... where the coordinates form some
kind of spline to specify the resulting color...

Would that help ? ;)

Bye,
Skybuck ;) :)
