Can i getColor of a color resource for a special configuration?

For example think we have a color resource in values/colors.xml as:

<color name="navigation_drawer_overlay">#66000000</color>

And the same color resource in values-night/colors.xml as:

<color name="navigation_drawer_overlay">#33AAAAAA</color>

By default when i fetch this color in java source codes: 

ContextCompat.getColor(getContext(), R.color.navigation_drawer_overlay);

It will fetch base on automatic configuration detection.

But i want to fetch special configuration (in my case values-night version)

Is there a way to force fetch resource of my desire configuration?

Can i force fetch -night color resource?

Based on answer by @user3094449

But with some modification

The correct constant for night mode is UI_MODE_NIGHT_YES, not NIGHT_MODE_YES.

private static Context getNightContext(Context fromContext) {
    Configuration configuration = new Configuration(fromContext.getResources().getConfiguration());
    configuration.uiMode = Configuration.UI_MODE_NIGHT_YES; // set night mode
    return fromContext.createConfigurationContext(configuration);
}

For several years later, there is a solution:

    private static Context getNightContext(Context fromContext) {
        Configuration configuration = new Configuration(fromContext.getResources().getConfiguration());
        configuration.uiMode = UI_MODE_NIGHT_YES; // set night mode
        return fromContext.createConfigurationContext(configuration);
    }

    // try to get the color from nightContext

you can try this workaround:

1) set two colors inside colors.xml like this:

<color name="navigation_drawer_overlay_day">#66000000</color>
<color name="navigation_drawer_overlay_night">#33AAAAAA</color>

2) Inside class when you need to change color do this:

switch (AppCompatDelegate.getDefaultNightMode()) {

            case AppCompatDelegate.MODE_NIGHT_YES:

                ContextCompat.getColor(getContext(), R.color.navigation_drawer_overlay_night);

                break;

            case AppCompatDelegate.MODE_NIGHT_NO:

                ContextCompat.getColor(getContext(), R.color.navigation_drawer_overlay_day);

                break;
        }
