Re: User Spaces vs. Generic Spaces

DeviceRGB, CMYK, & Gray color spaces are deprecated. You should always use GenericRGB, etc. instead. GenericRGB represents an ideal 1.8 gamma Mac color space that all monitors strive to achieve. Think of it similar to sRGB but different gamma.

Sometimes, especially in prepress, users want to specify color with exact CMYK values, which should not be corrected (changed) in any way.


It seems that on Tiger (at least with Apple's color-picker panel) device CMYK is still in effect - if one chooses CMYK color via standard color picker (in Cocoa app), the result is NSDeviceCMKY colorspace, and in EPS or PDF output (saved via Cocoa) the color is set via setcmyk command, which is device-dependent. Which is very well, since colors in CMYK space typically must remain the same (numerically) as specified.

Is this going to remain the same? Or is this just a feature of Cocoa apps?
