Have wallpaper background colors match your image
Authored by: arcticmac on Feb 01, '11 10:32:31AM

I wasn't able to duplicate your success exactly. What I found was that it doesn't matter which source you pick your color from, so much as what color profile you set the color picker panel to use. Specifically, on the color I was using, both DCM and the color picker would read out the same number, and would set the color profile as "Device RGB", and it would be wrong. However if I changed to the "Generic RGB" profile and then type in the same numbers (which I can just read out of the color picker; no need for DCM unless you can't remember three numbers for 10 seconds), THEN it works correctly.

As far as the bug goes, it looks like the issue is that the code that draws the desktop is different from the code that's doing the "preview" view in the pane. If you look at the preview, it matches fine when you just use the color picker's dropper, but then the desktop gets it wrong, and when the desktop looks right, the color picker looks wrong. I suspect that what's going on is that the prefpane reads/writes three RGB values to the plist file, and then the code that displays the color reads the values out, but doesn't take into account what color profile they were set under. (which, if you look, seems not to be recorded in the pref file anyway).
