 In case you are interested, here is the spectral values for GTI N8
As per the Lindbloom Calculator this comes out to an RGB value of 195.83 197.76 196.33 with a Yxy of 55.993290 0.312233 0.330739. EasyRGB comes out to a value of 196 198 196, which is obviously rounded from the Lindbloom figures and I consider both to be accurate.
Our target D65 neutral value is 0.3127 0.3290 , so it is close but falls slightly above D65 and left ever so slightly into green territory. This isn't a large move, but it isn't dead on like I expected it to be. It is still one of the nicer grays I have seen, albeit a bit more expensive than most people will want to pay. $25 isn't bad though for a pint and Kenyee seemed to get good distance out of it coverage wise.
Maybe these values help with what you guys are seeing.

You know Bill, you make me feel better and better each day! Now that I've finally read the
DIY Painted Screens thread and most of the
neutral gray thread it seems like my FG is pretty much on par colorwise with a neutral manufactured screen. For those of you reading this and wondering "huh?", follow along with me. Let me start off by saying that Bill has been at this DIY screen stuff for well over a year now and he's dotted most of his i's and t's. One of the things we're discussing in this thread is the calibration of a camera. And this is probably something that should be accomplished when shooting screen shots. Most pros do so now with a neutral gray reference card in their first shot or two. They then use this to set the color balance on all succeeding shots within Photoshop or whatever software they're using, using that reference shot with the neutral gray card in it. This takes the place of manual white balancing, which when using a standard piece of paper can give you awful results such as this:
That's one heck of a blue push! The lights in the hallway are incandescents - not fluorescents! This blue push is a result of the bleaching of normal printer paper, giving it the bluish push. They say you can use a pringles lid to calibrate white balance manually but Pringles lids have been changed to clear. I've tried tissue paper and coffee filters with the same results as above. But I'm really digressing here. So in the links above I'm told that professional manufactured screens generally have a red and blue push - they lack a bit of green to them. Well so does my Fashion Grey Laminate. It's basically a $2000+ screen for about $200! For comparison Fashion Grey's numbers are Red-195 Green-188 Blue-194.
Enough of my tangent. I'll be doing further testing this week when my Whibal card shows up. I'll have posts here and I intend to continue my comparison of Fashion Grey and Designer White then.
