It´s true that colormanagement is really a beast as long as one has a “color management gap” in the workflow. I.e if you use it, you have to implement it in the whole production pipeline and this includes the print shop as well. But, imo after one has gotten a grip on it, it amortizes the effort. As I´ve written before I ´ve been working with lighting simulations, and the only chance to achieve a reliable visual representation is, to base on a defined color space, in this case sRGB. This is also part of the technical obligation. We can deliver our renderings with the remark that they are meant to be viewed in a sRGB environment. If the customer has only monitors which gives weird colors, we would be in hell not to have a reference.

What I´ve meant with

And if you have a monitor that is not calibrated to sRGB than you will pick wrong colors…

is, that you cannot rely on the color of you monitor if it´s not calibrated. E.g. if you have a reddish shift and you would like to pick a neutral gray color you will probably pick a color which is shifted to the green. This is of course only the case when one is picking colors due to it´s visual appearance onscreen.
