FYI:
Sometimes:
Activity activity = getActivity()
doesn't work correctly.
It can failed when fragment is detached from activity.
Such situations occure very! often (at least in my code for example :-) )
For resolving the issue you can implement next functionality in Your ColorPickerDialog source:

protected ActivityEnabledListener aeListener;

    protected void getAvailableActivity(ActivityEnabledListener listener){
        if (getActivity() == null){
            aeListener = listener;
        } else {
            listener.onActivityEnabled(getActivity());
        }
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) activity);
            aeListener = null;
        }
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) context);
            aeListener = null;
        }
    }

public interface ActivityEnabledListener {
    void onActivityEnabled(FragmentActivity activity);
}

and then replace using getActivity() method with following code:

getAvailableActivity(new ActivityEnabledListener() {
                    @Override
                    public void onActivityEnabled(FragmentActivity activity) {
                        // You can use activity object safely here 
                    }
                });
