how green is the green in the sRGB color space.

[xMax]

i hear that the CIE (1931) diagram is innacurate and exagerates the greenish yellow hue of the green.

but if we took a circle and assumed the top point is green, while the lower left and lower right points were red and blue respectively, and since the red and blue seem to be extremely red and extremely blue, respectively, then how many degrees off would the green be to the left, which is the yellowish side.

but i cant imagin anybody could answer this question.

and that brings me to the main question: are there any monitors which allow for manual setting of the chromaticity values, so that any gamut within the maximum gamut available on the monitor can be set. this is like the triangle in the CIE xy diagrams. another words, are there any monitors which allow the user to manually set the red green and blue points anywhere within the maximum available gamut the monitor has to offer, so that i would be able to set any triangle in the CIE diagram, and thus fix the greenish yellow issue, if it does exist.

dont ask me why im asking for these questions. i dont have a simple explanation.

note to self: if no one responds, then ask question concerning variable chromaticity value adjustments as the head question in the title to a new post.

Eh remember that the whole color thing is somewhat subjective. I mean, what's green? If you look at a spectrum, it goes from yellow to some weird color to blue. How do you define where in it is considered the "greenest"? The guy just took some volunteers, asked them if they can see stuff, and from that data popped out the diagram. It's somewhat different for different people.

You can probably calculate how many degrees off you are if you specified a specific profile (say sRGB), looked up the definitions, then look for the technical definitions for the colors (i.e. on a color wheel). But that's somewhat beyond my laziness factor to do.

In terms of what you're asking about though, I would guess something along the lines of the adjustable RGB values in the OSD. But in terms of the triangle, that only brings the points inwards to or outwards from the center, and does not rotate them. Otherwise, it's a matter of choosing the correct monitor; the points are determined by the materials used as the color filters, which vary between manufacturers, thus resulting in inherently different color triangles. There's also the issue of the LC material itself having different performance for different wavelengths.

Theoretically, you can rotate the points, by having the video card do a rotational matrix on the values. So say, if we looked at things in terms of (red, green, blue), then you could define (255, 0, 0) => (230, 20, 5) and so on for the different values. What this means is that if the video card sends (255, 0, 0) to the monitor's drivers, then they would really send to the monitor (230, 20, 5) instead (note that for maximum triangle size though you'd want one of the values to be at 0, so it should really be like (255, 0, 0) => (230, 25, 0) or something like that). It'd be easy enough to scale it, so that (127, 0, 0) => (115, 12, 0), etc.

I wouldn't really know what monitor allows for that though. Maybe some of those color calibration monitors, but I have no idea if they simply adjust the RGB values on your OSD, or if there's something more tricky going on. Not something I'd want to bet that much money on.

hmm... color calibration monitors, if they exist, is what i would need to get. but i would only do this after understanding the saturation values of the sRGB color space. that is, what is the sturation of each sub pixel that uses the sRGB space. or what is the typical saturation since they will likely vary. because it seems that green is less saturated, and this could be a problem for me, perhaps requiring a color calibration monitor or an adobe RGB. but before i go off spending that cash, i need to make sure.

the problem is that i cant seem to find the info on saturation of color filters for srgb color space on the internet. and thats why im posting.
