Colors on monitors are very hard to match

Who is "You"?

At any rate, since computer monitors aren't standardized, there's no way to tell what you are seeing. I have this displayed on 2 monitors now (the screen on my Dell laptop and an external Samsung monitor), and the colors are close (because I have matched them well--I've worked in I.T.), but they are not exact matches, and the Samsung shows it darker than the laptop. And the reality is that neither of them may be showing the true color of the original.

Just go to a paint store and look at the samples. Pick one.
