Hi,
I know recently Insanity's projector has been getting a lot of praise for its white produced by adding a dedicated yellow module to the established RGB line up.
It seems that tv manufacturer's are starting to agree with this approach with Sharp now adopting RGBY.
Apparently adding Yellow aslo ups the number of possible colours from 16.9 million to over a trillion.
Small article on the sharp tv here: http://www.tomsguide.com/us/Quattron...news-6228.html
Should we all be heading for RGBY projectors?
