Are you aware that Firefox does not have color management turned on by default? You have to go in there and enabvle it manually. If you don't know how, then get a free Firefox Add-on named "Color Management" to do it for you.
G. Ballard is very aware of his site and very savvy about color management. If you actually read everything on the entire site, carefully, it will become clear to you.
"Whacked"—as amply explained there—is an arbitrarily "whacked" profile created by the author of the site in order to illustrate a point or two.
Face it: you are using an obsolete Mac with an equally obsolete version of OS X, and attempting to use a non-Apple monitor with it.
Try experimenting with ColorSync:
You can read more about RGB here:
and about Colorsync here (invented by Apple) here:
as well as Apple's version:
In most graphics applications (like those from Adobe) you can switch between Colorsync and RGB profiles, much much depends on your printer.
There are two basically different kind of printers which can be selected - RGB printers and CMYK printers. Usually a home base printer will be an RGB printer, which means, it prints with the colors Red, Green and Blue - sometimes with three, often now with more than three colors, but all of them are shades of Red, Green and Blue. I have chosen RGB and therefore I get a printer icon, which happens to be exactly the printer I used for this review, an inexpensive Epson Stylus Photo 820, and you can see the three colors as puddles in front of the printer to make sure that you have selected an RGB printer.
That was taken from this article:
Colorsync works 'under the hood' but most printer drivers allow switching between RGB and CMYK. You will find the Colorsync application in your Utilities Folder, and it is worth exploring.
To quote David Pogue:
Computers aren't great with color. Each device you use to create and print digital images 'sees' color a little bit differently... colors are often inconsistent as a print job moves from design to proof to press.
Colorsync attempts to sort out this mess, serving as a translator between all the different pieces of hardware in your workflow. For this to work, each device (scanner, monitor, printer, digital camera, copier, proofer etc) has to be calibrated with a unique [i]Colorsync Profile[/i] - a file that tells your Mac exactly how it defines colors.
Most of the people who lose sleep over color fidelity are those who do commercial color scanning and printing, where 'off' colors are a big deal.
Colorsync profiles for many color printers, scanners and monitors come built into OS X. When you but equipment from, say, Kodak, Agra or Pantone, you may get additional profiles. If your equipment didn't come with a Colorsync profile visit Profile Central at http://www.chromix.com where hundreds of model-specific profiles are available for downloading (but they are not free). You put new profiles into the Library/Colorsync/Profiles folder.
In professional graphics work, a Colorsync profile is often embedded right in the photo, making all this automatic. Using the Colorsync Utility Program you can specify which Colorsync profile each of your gadgets should use. Click the devices button, open the category for your device (scanner, camera, display, printer or proofer), click the model you have, and use the Current Profile pop-up menu to assign a profile to it.
Professional graphics people have been known to go insane doing all this. For the rest of us, where an approximation will do, just select RGB and some decent paper, and hope for the best!
