Just found this very interesting thing on the web regarding the above. Have a look at the background of the following webpage: Most surprisingly, it does look (at least to my eyes and on my screen) like a smooth transition from blue to yellow _without_ an obvious green or grey in between. To see it more clearly, you can try saving the background image and opening it in your computer; it is a thin stripe in whose middle you will find the closest approximation to yellowblue I've ever seen on a computer screen. Cheers, Javier
