Okay, it is a little primitive, but it's the easiest way I know to illustrate why the Sun's light gets warmer as its angle in the sky is reduced. When straight overhead, the light rays from the Sun travel through much less atmosphere than when the Sun is on the horizon.
This is the primary reason that both the Sun's intensity and color are affected by the ...

The color of sunlight reaching the surface changes based on the thickness and quality (in terms of things like particulate matter and water vapor suspended in it) of the air it passes through. Whether the sun is at an angle 30ยบ above the horizon because it is noon in winter at a high latitude or because it is 4 p.m. in the tropics doesn't make much ...

The most significant difference is the dynamic range required to capture the sun areas and the shadow areas. The colour temperature you always have to manage, no matter what, but the dynamic range can be hard to manage, because the light in e.g. California vs Denmark can be the difference between being too hard without shooting HDR in California, vs being ...

Latitude doesn't directly change the sun's light in any way. The angle of the sunlight and the amount of atmosphere it has to pass through both indirectly impact the intensity and color of the light, but this shouldn't have a significant impact on taking photos as long as you properly meter and white balance.
The bigger direct concern would be the angle of ...

Ok, here are the answers to your questions one by one
1) There is a change on the color or white balance or gamma or something taking one shot for example at tropic, at equator and pole, BECAUSE the light from sun changes in every latitude?
Yes, absolutely, but the difference is not more substantial than the difference between seasons or time of day.
2) ...

I wouldn't calibrate based on what the print looks like from them. I'd calibrate to a standard. It's going to be really really hard to find a CRT with good color these days as they basically don't exist anymore and most of what you can find is crappy left overs (those who have good CRTs tend to hold on to them).
If you can find a CRT, programs like Adobe ...

xvYCC is a particular clever way of encoding color data: it abuses the YCC representation by using previously-forbidden combinations of values to represent colors outside the gamut of the RGB space used in the YCC scheme. That is, some YCC tuples decode to colors with negative R G or B values. Previously these were simply illegal; in xvYCC these are ...

Have you been closing the application after printing? I'm not sure exactly what causes it, but when I was doing prints out of Lightroom the other day on my Pro-1 and I closed lightroom. The exact moment I closed the program, the print (mid-line) developed the problem you describe. Reprinting and not closing the program fixed the issue completely.
My ...
