Just found this very interesting thing on the web regarding the
above. Have a look at the background of the following webpage:
http://www.uni-koeln.de/phil-fak/indologie/tamil/mwd_search.html
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,
