What color space is the SpyderCHECKR / SpyderCHECKR 24 intended to represent?
The SpyderCHECKR 24 and the 48-patch SpyderCHECKR targets are not specific to one light source, color temperature or color space. They are spectrally neutral so the temperature of the light does not affect the color itself. However, they are designed to be very close to fully contained within the sRGB color space. When using either target with sRGB, AdobeRGB or other common color spaces there will be little or no clipping.
