I suppose the pistol pewter in my BR appears light because of the halogen lighting on the ceiling. I have the lights aligned so that they skim the ceiling, casting a glow on the walls. I would describe PP as a mid-toned grey; not too light, not too dark. I took a look at the photos of your kitchen again, and I think it would go well. And I think a half strength version would probably work well in the tv room. But eventually you just have to take the bull by the horns and try it. The photos people post are so small they can't convey everything people need for the best colour decision. The problem is complicated, moreover, by computer monitors -- they just don't give a completely accurate rendition of colour. So the comes a point where you gotta blow $40 for a gallon of paint and try it out. There's been a lot of "ink spilt" on the site lately over paint colours. Everyone's getting a bit frustrated trying to make their choices. And of course, when there's 3700 others sitting on their computers suggesting this choice or that, I can see how it would be overwhelming. There is a point where you just got to do it -- you have to risk not liking it, and you have to risk others not liking it. Hey, take look at my kitchen LOL. Now if that's not a risk, what is? As I stated in one of my other posts, I painted the east wall of my LR in 6 or 7 colours before I found the one colour that worked for me (at least for now!).
