SRM Color Impression Rendering with the deLange Formula

[ashman]

This is not a feature request, but I recently created an implementation of the deLange model (http://dx.doi.org/10.1016/B978-0-12-799954-8.00011-3) that can be used to color SRM values, and thought it might also be of interest to this community. The unique feature of this model is that it was derived from spectral analysis of 99 beers, rather than polynomial fits to the color gradients of an existing beer color guide. In addition, it formed the basis for the BJCP color guide and can also be adapted for specific beer glass widths, as the perceived color of beer darkens in wider glasses.

The implementation for several programming languages is available here: https://github.com/aschet/olfarve

Thanks, I saw this posted on reddit as well. Nice job Tom (unless you prefer Thomas?)! Thanks for sharing

Thank you, either way is fine! Yes, I have been knocking on some doors lately. When I learned that A.J. deLange has been working on this at least since 2000, I thought his work deserved some attention.
