Colors sample?
I think most colors will be ran with a private buy I'm doing, but it doesn't really matter anyway.
The Pantones are a guideline, simply because all of these are variables: your eyesight; your monitor color accuracy; my eyesight; my camera; my monitor color accuracy; my choice from what I see; the factory and their color accuracy (which will change throughout the monitors they use); their choice on what they think they can do; and finally, anodizing variables (which include between batches, and a whole lot more).
Basically, it's a waste of time. What you see if pretty much what you'll get.
The custom colors in 268 AG turned out really well when I'm comparing the color directly to my monitor. Now remember all the variables. I am very happy with how they turned out anyway, and I have no doubts this'll be any different.
