Thanks John!

I suspected the color chart was off by some measure but rather
surprised by the magnitude.  Being a test instrument, under ideal
conditions, it would be nice to hold the delta-e to under 1 (below
normal perception).  That DOES suggest another use for the Spectro
though.  Measure your chart and use THOSE numbers instead of the ones
supplied in the literature.

Thanks again
