Now just to make it interesting, could you convert these four sets of numbers to RGB, and describe the method used?

Thanks,

Sorry Garry, I don't know how to do that, better ask Bill how he did it.

You might find something here: http://www.brucelindbloom.com/index....alculator.html

For finding the L*a*b* and RGB values I use in my Spectral Reflectance Charts, I copy the output from my spectrophotometer into the spreadsheet that can be found at the link above by clicking on the MATH button at the top of the page and then on the Calculators and Spreadsheets link.

There is loads of good stuff at Lindbloom, but almost all of it is above my poor cognitive abilities.
