Well, but then it's not really a calibration but just a profile that suits your needs and we're back to the problem where everyone uses different hardware or settings because it looks good to him.

But I get what you mean now.
The reason I asked is because many say the colors are off or whatever but the chain is mostly broken. Working in the field of graphics I can only say it's a lost battle to begin with:
- Everyone perceives colors and shades of light differently.
- Photos (for reference) are also mostly uncalibrated and even if they are calibrated... there's no camera out there able to capture the full spectrum.
- The game can't really simulate all weather effects (which have a HUGE impact on far distance viewing.
- One of the most important things: The diplay technology of screens used today is still inferior because of enforced background lighting plus the lighting that is added from the "real world" lighting (e.g. lamps, sun etc.) which affects the image even on non-glare screens (which simply diffuse light better than glare screens).
Personally I believe only a very tiny fraction of players actually has access to a screen good enough and calibrated to even make a rough assumption. But then again, it's a very subjective topic.
Personally, when I go out on a sunny day and look at the colors of grass etc. it's very vivid. Even in the UK and Ireland (was there for a holiday).
The mossy, washed out, colors the op want's to have are definately not real.
To me the current CloD engine is really enjoyable.
