CM - didn't mean to imply that you haven't, though I see you don't mention universal in your response.
You mention different shades - I can see your point as to how they would crush whites etc, and I appreciate your work bringing out a new angle on the grey question.
My question was specifically about Glidden "universal grey". It is not lighter or darker then ME, in fact it is the EXACT SAME SHADE, just without the blue and green added (when you look at the factory ME recipie.) Now, the BG may be what makes ME a hit, but I was curious as to what a completely neutral grey of exactly same shade from the same manufacturer would do.
I will test this myself if Dell ever deigns to send me my X1. I used a perfectly legit coupon (one they sent me) to get it for $899 and they telling me it could be three weeks. (of course if you're willing to pay full price they'll ship it tomorrow.) I have bought hundreds of thousands worth of systems from Dell over the years for various campaigns and organizations, because in this land of the blind I am the one eyed man when it comes to computers. Because Dell thought it was worthwhile to screw me on this one purchase I will NEVER buy from these slick SOBs again. Ramming a hot poker through Michael Dell's eye seems unlikely to happen, but one can dream.
