In case anyone is interested in another solution without using a Selector XML resource file, here is one somehow based on @Panayiotis' answer.

Add the below methods to the SlidingTabStrip.java class:

public void setTabTitlesTextColor(int selectedPosition) {
    for (int i = 0; i < getChildCount(); i++) {
        if (TextView.class.isInstance(getChildAt(i))) {
            ((TextView) getChildAt(i)).setTextColor((selectedPosition == i) ? getTabColorizer().getIndicatorColor(i) : Color.argb(90, 0,0,0)  );
        }
    }
}

public SlidingTabLayout.TabColorizer getTabColorizer() {
    if (mCustomTabColorizer != null)
        return mCustomTabColorizer;
    else
        return mDefaultTabColorizer;
}

Call the newly created setTabTitlesTextColor() method in onPageSelected and setViewPager on the SlidingTabLayout.java class as below:

public void setViewPager(ViewPager viewPager) {
    mTabStrip.removeAllViews();

    mViewPager = viewPager;
    if (viewPager != null) {
        viewPager.setOnPageChangeListener(new InternalViewPagerListener());
        populateTabStrip();
        mTabStrip.setTabTitlesTextColor(viewPager.getCurrentItem());
    }
}

@Override
    public void onPageSelected(int position) {
        if (mScrollState == ViewPager.SCROLL_STATE_IDLE) {
            mTabStrip.onViewPagerPageChanged(position, 0f);
            scrollToTab(position, 0);
        }

        mTabStrip.setTabTitlesTextColor(position);

        if (mViewPagerPageChangeListener != null) {
            mViewPagerPageChangeListener.onPageSelected(position);
        }
    }
