colex is a software package for displaying colours sampled from an image, in different CIE spaces, for comparing different formulations of the hue, and for studying the effects of system-dependent parameters. It was also my first attempt at multi-threaded programming. colex depends on plan9port and libtiff, and features an alternative (Plan 9 style) GUI. The source code is available here as a 21KiB tar.gz archive. (screenshot [png 411KiB])
