Re: User Spaces vs. Generic Spaces

Brendan does  a good job describing the issue.

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.

Are there performance impacts between the various colorspaces ?

For example we've been using (old code - I plan to update it) DeviceRGB, recently our marketing people noticed that some of our UI doesn't match the photoshop produced art they're used to seeing and I determined that the photoshop art was was using sRGB. I made the minor change to tweak our code to use the alternative colorspace but saw such a dramatic performance loss i backed my changes out again (at least for now 8-)

Any thoughts/suggestions ?
