BYK has organized free webinars on instrumental color measurement. Please see http://www.byk.com/en/press-events/webinars.html to subscribe. The company has kindly determined the time zones for the lecture depending on where you live across the globe. There are also some hand-outs at
http://www.byk.com/en/support/instruments/technical-information/color-information.html some are basic, others a little more technical or further afield (example factors in auto paint quality) that still might be useful.
