Well so far I have learned that blue variations are the hardest to detect.
Also green pushes are the easiest to detect.
Green, in fact, is the easiest to detect because it's the color that controls how much light/brightness that we see. Adjust ONLY the green on your device way up. If you could measure the lumens, they would increase subsantially. Do that with blue, not so much. With red, even less. Regardless of how bad your picture looks....They aren't pushes, they are changes in Luminance.
I guess what this experiment shows is that if we were to try and compare a gray paint to a reference neutral gray then we would be less likely to detect a blue shift.......
Ah, see your problem is that you are testing a blue agaist a "so called" neutral background. I think if you test just the background,, you would see that we are more sensitive to the change in that color and not the intensity of the exisiting tests. That's why we always hear about a blue push. I.E.>>>>>
Which poses an interesting question: Why do we never hear about anything but a blue push?
Well let's get right to the point then. I never observed a blue push so to speak with Behr "Silver Screen". I did observe that it had a redish look to it though. The complaints that I heard were always with regard to reds not looking right. I believe the problems some people observed were due to the variations in the spectral reflectance curve in the red region.
Hmmm, could it be that most Projector Lamps have a red push to them already?...? AND.....people tried to correct by overdriving their saturation to compensate?
It also has occurred to me that if UPW is blue deficient to start with at 248 248 241 then adding Lamp Black alone should be helping to make it more RGB neutral
Did you ever think that maybe UPW is balanced already and that's why MANY people use it? Remember adding a little red or green won't be as noticable to the eye. Change or add more blue and you'll see it. OHHHH, Blue Push again.
Why do the numbers have to equal on paper when our eyes don't see the primary colors equally.
Maybe people need to spend some time in the calibration thread and see what really happens when a color is thrown out of balance. with all of the money everyone has spent on experimenting, one could have easily bought any of the home user calibration set ups and not had to worry it their screen was neutral gray or pure white. A person can even get the software free.
I think you guys spend more time talking shop than getting in your cars and DRIVING THEM. For Pete's sake, go get a life...............
