Excellent info from both Bart and Mark. I plan to archive both. Unfortunately it will fall on Franz's deaf ears. He really isn't interested in getting the facts. The post he made on PhotoNet the same day as the post here was locked down due to his stubbornness and inability to link this to anything related to photography. I tried to explain to him that by the nature of a color being correlated, we're talking about a possible range of possible colors.
His reply is classic Franz:
Calculating CCT from the x and y coordinates is rather complicated and different calculators use different algorithms, resulting in slightly different answers. However, these answers should not be more than a couple of Ks apart, and the answers from the three calculators that I used are within that range. However, the SoLux CCT number is way off, by about 44K, so that begs the question that SoLux sofar hasn't answered.
Answer: The Solux values
are wrong! He's certain despite asking, that the values should be within a few K but since that dismisses the Solux values, he can't accept it. Apparently even Solux is ignoring him as should we. Troll alert!
