Currently Being ModeratedMar 26, 2009 10:41 AM (in response to James O\'Loughlin)I thought I had a similar problem with Gimp, using the color selection eye-dropper, but it turned out that I was using the wrong end of the eye-dropper. I was using the upper-right rectangle, not the eye-dropper point on the lower left.MacBookPro3,1-17"Core2Duo/VistaUlt64SP1; MacBookPro1,1-15"/XPProSP3; Dual G5/XPP, Mac OS X (10.5.6), Homebrew 3GHz ASUS PC, Dell Inspiron8k, Abacus, Sliderule, HP-50G
Currently Being ModeratedMar 26, 2009 12:21 PM (in response to nerowolfe)thanks for the idea. actually, i'm not using any eye-drop, just dragging the cursor in the color wheel. you can see the little dot in the "RED" area and the displayed color is brownish...amiga
Currently Being ModeratedJun 9, 2009 2:53 PM (in response to James O\'Loughlin)I have no answer, but I'm glad I found someone with the same problem.
I'm also glad you suggested using a different account. I created a new account, and found that the problem disappeared.
I can say that this bizarre behavior started when I swapped out my Syncmaster for a Dell 2408wfp wide-gamut display. The latter was a headache to get calibrated properly---it needed to go through an eye-one hardware calibration to be useable. Of course, this just makes things doubly odd that simply creating a new user would fix the problem.
I will try pecking around some more to see what the problem could be by looking through ~/Library, and will report back if I find anything worthwhile.mac mini, Mac OS X (10.5.7)
Currently Being ModeratedJun 9, 2009 5:19 PM (in response to Bill Rising)Here are some guesses based on what is going on:
The funny brown color is indeed related to having a new display (but the brown seems like it can be cleaned up, see below).
The problem seems to be a difference between the 'device rgb' space and the 'calibrated rgb' space.
It appears that if you pick a color from the color wheel, it is picking a color from the 'calibrated rgb' space---and from my miserable experience trying to use the color sync software to calibrate my wide gamut monitor, I have doubts about colorsync with such monitors. The reason I guess this is from calibrated rgb space is the tooltip is 'Generic rgb' when held over the color bar at the top.
Contrast this with picking a color from the spectrum image (by default the fourth button from the left). If you pick any color off this, you'll notice that the color bar at the top has its upper right corner clipped off. The tooltip now reads 'device rgb', meaning that the color being displayed is one which is not passed through colorsync. Here it is possible to pick a bright red, and things look bright red. If the application is using the calibration rgb color space, though, it will only use the colors as presented by the color wheel.
As for the brown, I got rid of the color shift from red to brown by giving myself the same advice I give my 2000-mile distant mom when I have no answer: zap the PRAM (reboot holding command-option-P-R, and let the machine boing at least 7 times). After doing this, the color bar was red when red was selected in the color wheel---it was not bright red, but it was no longer brown. It matches the red in the new account, at least.
Do you have a wide-gamut display?mac mini, Mac OS X (10.5.7), wide gamut looks nice but doesn't play well...
