Google Material You: How can we use the same Color Accent than system+Google Apps?

I have read the "documentation" to find the reference to accent color: https://developer.android.com/reference/android/R.color#system_accent1_0

But after implementing it in my application, I am not happy with the results and really like the Google implementation. (See screenshot below)

I have tried to display all colors in a sample application (the one on the left) and cannot find the same color than Google apps on the right (Phone, Gmail, Drive)

Is Google implementing a custom / proprietary implementation? Did I missed something?

Thank a lot for any help to find the right colors to use for my ActionBar, FAB, and other items.

Solution
    1. First of all most of the colors have transparency so it will be affected by background color, in their implementation, they used a dark brown color, which will affect some colors if there is transparency.
    2. Some of the colors are identical see the image.
