New subject: Isocoated vs EuroscaleCoated vs. EuropeIsocoatedFogr a27

      Hello 

In Real World Color Management (page 71), there is comments about LAB
limitations. It shows hue shift especially in blue region. So this might be
coming from imperfection of LAB-space. Has Adobe and Gretag taken this hue
shift into consideration when designing their profile software?

 L-level of

  ISOcoated's relative colour is almost on the
line.

 However how we experience the colours is another story...
 Precisely.
