For a year I was in the US delegation for ISO/IEC JTC 1/SC 29/WG 11 (MPEG) and specifically contributed to the section on color vision deficiencies in Part 7 (Digital Item Adaptation) of MPEG-21. I recently gave an invited talk discussing among others the issues of color readability (see http://www.hpl.hp.com/techreports/ 2004/ HPL-2004-236.html), and am currently involved in psychophysical experiments to determine the contrast threshold for the readability of colored text on colored background being conducted at CNR by Silvia Zuffi.
