A big part of the problem is the lack of effective communication and
documentation between developers and Apple. I'd bet that the reason so
many developers aren't doing the right thing with color management in
their applications is because of the lack of adequate documentation
explaining how to do it correctly. So far the situation from the end
user perspective hasn't improved much with successive releases of the
OS.
That is for certain. There is the "grand scheme" PR stuff. There is the low-level API docs that tell how the little pieces work. But there is absolutely nothing, documentation or example, that shows how to put the pieces together to implement the grand scheme. And that's the good news. The bad news is what documentation does exist is often simply deceptive. From the documentation for the Cocoa NSColor class:
There are three kinds of color spaces in the Application Kit:
• Device-dependent. This means that a given color might not look the same on different displays and printers. The components of a device-dependent color correspond to the inks in a printer or the electron guns in a monitor. Because printer inks and screen phosphors vary from device to device, you can’t expect a consistent color from a device-dependent color space.
• Device-independent, also known as calibrated. With this sort of color space, a given color should look the same on all devices.
*I* think it would have been nice to add a line in the nature of "Under Construction !! Not Really Hooked Up Yet !! Watch This Space !! Coming Soon !!" somewhere in there, but then again maybe I'm too sensitive about having my time wasted.
A bit of a shame since I don't think it actually requires that much code to do properly.
