Would you prefer it if we were all looking at different numbers? How do you think that might help? Its only when you can be sure that you are looking at the same numbers, that you have any kind of starting point. Try a simple test, create a grey document, with equal RGB values, then examine it on your screen. Is it pure grey? How do you know? Or does it just appear grey, because of the other colours around it. (remember the brown squares site mentioned earlier?) you may well think it looks grey, but you can't be sure, you have nothing to compare it with. You know that it is pure grey, from the numbers, but it should also appear pure grey on screen. One of my powerbooks, would give me a lovely magenta/grey using this test. How do I know it was magenta and not just my eyes? Well you can use the Digital Color Meter, in OS9 and OSX, to give you an accurate readout, or compare it to a correctly profiled and verified screen, or a verified print. A good purchase would be to buy a Print Verification kit from that "lovely" Neil Barstow, and compare his supplied screen image, with the supplied print. They should be identical. I would imagine, that unless your screen is properly profiled, it won't be. I've spent over �3000 on profiling gear over the last couple of years, and a lot of time. But that print kit, was one of the best purchases. Because even when you have your Eye-One and have profiled your screen, you have no proof that it is actually correct, without something to compare the results to. When you get to grips with this stuff, you'll understand and appreciate "profiling" and then suffer at least a year stressing about it, spending lots of money on it etc. etc. Its a great learning curve, with many a sleepless night. But at the end of the learning curve (or at least part way through it) you'll have the full hallelujah moment, and understand enough, to know what you do need to worry about, and what you don't.
