    LAB color values

    Dear all, i'm newbie to color proofing and needs confirmation if LAB color values are really machine independent?.. Means they will be displaying constant color values everywhere regardless of the machine profile. i.e. unline rgb or cmyk?

    Thanks!

    Correct. An L*a*b* number represents the exact color. Whereas a CMYK/RGB colorspace number is the color value in that particular space that represents the L*a*b* color.

    Sort of. It is machine independent, but the actual colour seen will depend on the viewing conditions, context and adaptation.
    For most applications Lab is the most practical way of getting reasonably consistent colours across devices.
    For more accuracy you can use CIECAM02, but that is too complicated for most applications.

    Well I was keeping it simple to the question.

    CIE L*a*b* (CIELAB) describes all the colors visible to the human eye and was created to serve as a device-independent model to be used as a reference.

    Forget bad lighting, back monitor calibration, bad printer ICC, etc. It still is a pin-point to color in the spectrum. Not CMYK or RGB.
