Cat,
I went with 3 different vinyl samples and 3 different grills to mix and match. I found in general that the samples were redder than the image on my monitor. So the one I thought I would pick to match my cherry furniture downstairs is not the one that I went with. I acutally did get a fairly close match - especially in incandescent light. Natural sun light the match is a bit off but not much. The technical term is Metamarizing when the object changes color in different light.
