Talking about colour gamut range

[Aussie Bloke]

I've been reading the responses to the 15GP22 Owner Pole and been interested with the talk about the gamut range of a 15GP22 opposed to a modern CRT so thought I'd continue the thread as a separate topic.

Reading Pete's response and looking at the gamut chart on his site with the ranges of the early colour TV sets opposed to a modern CRT, I'm amazed how much less gamut range todays CRTs have.

I am wondering why is it with todays technology do we not make CRTs/plasma/LCD screens with at least the gamut of a 15GP22???

Also one thing that has bugged me years ago I remember is I was noticing I'm not seeing emerald greens when I scan pictures with those colours, they turn out to be more yellowed than emerald, and a good example was the UK 12p queen head stamp http://paulreed.me.uk/Images/stamps/12p%20-1.jpg . This stamp has very very nice emerald green colour too it but comes up as more of a yellowish green when scanned! And with aqua colours they don't show up as a nice strong blue green on a computer monitor either.

I can imagine that 12p stamp if displayed on a 15GP22 CRT would come up with its original emerald green coloul. This would be a good experiment for CT-100 owners to try out, displaying a 12p queen head stamp on their sets and see if they can see the original emerald greens.
