Hi c0elacanth,
First and foremost, you need a
good monitor profile. There's the cheap way, and the fairly inexpensive way.
Cheap (free) method: Open the System Preferences and click on Display. Then click the Color tab. Click on the "Calibrate..." button. You may notice your monitor change color and/or brightness. Turn the check box on for Expert Mode. Click Continue and follow the onscreen instructions. Of course, you've tried this and seen that it doesn't work very well.
The fairly inexpensive method: When it comes to calibrating your monitor, there simply is no replacement for a hardware/software solution such as the X-Rite
Optix XR monitor calibrator. If you do a lot of prints, $300 is a cheap investment for color matching.
Why do this rather than the free method?
No matter how much you move the sliders or other controls around in the free method, your Mac still
does not know what the phosphors of your monitor actually look like. All you're doing in the Monitors control panel is shifting the preset LAB values of a basic profile. This produces a profile that is
still not based on your monitor's actual display. What a good colorimeter and its software will do, such as the Monaco Optix XR, is read the real LAB values the RGB phosphors of your monitor are capable of displaying and then create a profile based on those values.
For either method you choose, the settings for white point and gamma depend on what you can live with. The default gamma for the Mac is normally 1.8. This gamma most closely simulates the reflective density of paper. Most Windows computers use a default gamma of 2.2. This a much richer and darker gamma, but it's also pretty much impossible to reproduce on paper; photographic, inkjet or otherwise.
For white point, the default is 6500K, which is daylight white. Again though, this is a very bright bluish white that cannot be reproduced with paper. A white point of 5000K is much closer to what you can print in regards to light, vibrant colors and is closer to paper white. The higher (and bluer), the white point, the brighter and richer light colors become on screen but gets you further from paper white.
About that 5000K white point. Compared to a default monitor setup, 5000K looks yellow in comparison though it's actually just neutral. It may take you a little while to get used to after looking at a 6500K screen for years. If using the free method produces an orange colored white when you set it to 5000K, you're actually looking at a white point much lower than 5000K. That's because the free method has no idea where you have the white point on your monitor set to. If it's already set to a low Kelvin point, then dropping the slider to 5000K may give you something more like 4000K, which is orange. If it still looks too blue, then your monitor is probably set to 9500K and moving the slider to 5000K is leaving you somewhere around 6500K.
In other words, the free method is practically useless. Not really trying that hard to push you into purchasing a monitor calibrator, just presenting the facts.
So, your choices are:
1) Use a 6500K white point along with a 2.2 gamma for images on screen that really pop, but will look flat and with less color saturation on your prints in comparison.
2) Use a 5000K white point along with a 1.8 gamma that will cause your monitor to look somewhat flatter and a bit less colorful, but will match your prints
much closer as your monitor is set up to more closely simulate a print.
Actually, if you
are in printing, then you need to use the D50 setting rather than 5000K. While both use a 5000K white point, the method used to create it is different, resulting in an equally, but slightly different gray ramp.
