I find the color thing a little amusing - well mostly when someone designs something that is meant to be viewed on a monitor/tv screen as everyone callibrates the colors, contrast & temp differently, then of course you have people who run apps like fl.ux (I used to, but it started annoying me as the colors just looked weird half the time & the mac version of fl.ux was even worse).
I know what you mean. Sometimes people use colours as a religion :-)
Other doesn't care if the skin is red or yellow or green...
If you are designing for flyers, posters, photos that are to be printed out then I perfectly understand the need to adjust colors to realistically represent what the final printed out product should look like...
Yes, I am from the print world and the problem that the same picture looks different on different papers or screens is the reason to make calibration curves from every machine you want to use. But today the designers make strong colours (look at calendars, TV-magazins ans so on), sometimes the sky is BLUE, BLUE, BLUE and the water is BLUE, BLUE, BLUE... and house brick walls are RED, RED, RED and so on.
But if you want ro reproduce the Mona Lisa or another picture you need millions of nuances. You can reproduce a Turner painting if you want with only ten colours, but.... *lol* OK, today it's more easy with pdf and colour profiles than ten years ago (it's all sRGB today *lol*). The customer wants STRONG colours with 200% Magenta, 200 % Yellow and 200 % Cyan and 400% Black, but that's like fast food: too much, too candy, too simple...
I soon have this colour problem if I want to print my own photos on printer paper. Every brand name paper is different, every paper weightness is different (because of luminance), every ink is different. It's important how much ink is in the printer. How old is the paper. What's about humidity? You need 30 test prints ... and then the ink is empty
But of course: my monitors are older and they will be crashed some day...
It's off topic. But for example: if I use my 3D program to make a weight map for a character mesh, the monitor should be able to show differences between 13% green and 14% green. Or 67% green and 68% green. Or the same map using red colours... Using airbrush to make a picture you have to see the difference between 50% grey and 51% grey.... For watching a movie or using Visionaire you don't need a 500 Euro screen...
