I've tried just drawing this colour to a plain view, and I get no texture, just a pale "chino" sort of colour. Looking at what I get from this method in the debugger:
(NSColor *) $1 = 0x000000010983f850 NSCustomColorSpace sRGB IEC61966-2.1 colorspace 0.980392 0.941176 0.901961 1
This seems to be the colour I'm seeing. I would not really expect it to be in the sRGB colorspace, but the real giveaway is this - if I ask this colour for its -patternImage, it throws an exception, just as the documentation says it will IF IT HAS NO PATTERN IMAGE. Something's gone wrong delivering this colour to my app from the internals of Cocoa. But what?
