Marti, thank you for answering my long question! The context was that I was asked if there was a stand-alone program for generating ICC profiles. I didn't know of any, but realized that I could write a simple program. So I looked for values to use for primaries, white points, and tone curves. I found very good agreement on primaries and tone curves, not so much for white points. Plus I was puzzled by the "color-balanced/not color-balanced" results.
In case anyone is curious, the table below shows various D65 white point values: x y Source 0.312730 0.329020 Danny Pascale, "A Review of RGB Color Spaces" 0.312700 0.329001 AdobeRGB1998.icc profile 0.312700 0.329000 Adobe RGB (1998) Color Image Encoding 0.312700 0.329001 Argyllcms sRGB.icm profile 0.312727 0.329023 colormath.py ASTM 0.312727 0.329023 colormath.py Wyszecki & Stiles 0.312704 0.329023 http://color.org/chadtag.xalter 0.312727 0.329023 http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html 0.312727 0.329023 Hunter Lab ASTM E308 values, Insights on Color, Vol. 14, No. 2 0.312700 0.329100 LCMS API documentation, sRGB D65 0.312716 0.329001 V4 ICC Specs, B.2 Embedding ICC profiles in EPS files -- Elle Stone http://ninedegreesbelow.com - articles on color management & open source photography ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
