tl;dr:
ContextCompat.getColor(context, R.color.my_color)
Explanation:
You will need to use ContextCompat.getColor(), which is part of the Support V4 Library (it will work for all the previous APIs).
ContextCompat.getColor(context, R.color.my_color)
If you don't already use the Support Library, you will need to add the following line to the dependencies array inside your app build.gradle (note: it's optional if you already use the appcompat (V7) library):
compile 'com.android.support:support-v4:23.0.0' # or any version above
If you care about themes, the documentation specifies that:
Starting in M, the returned color will be styled for the specified Context's theme
