What is the Color Space of the Display Native Values on Digital Color Meter

Question

Does anyone know what is the Color Space of the Display Native Values on Digital Color Meter and how to get this color space as a NSColorSpace or a CGColorSpace object. Thanks.

Answer 1

I assume that that's NSColorSpace.deviceRGBColorSpace a.k.a. NSDeviceRGBColorSpace a.k.a. CGColorSpaceCreateDeviceRGB().

In other words, I think those are the actual values in the hardware framebuffer (modulo float vs. integer representation).

Answer 2

The "Display native values" color space is simply the active display profile.

Now how do we go about getting a hold it? We have two options:

1. NSScreen.colorSpace
2. CGDisplayCopyColorSpace — also see CGMainDisplayID()
