Can I affect the color of ripple touch feedback while targeting API 16?

Question

Is there a way to make a ripple have a darkening effect instead of lightening one?

I can set the background of a CardView to a darker color and clearly see the ripple feedback. However, my card normally has a white background. The ripple is almost invisible because it is only noticeable on top of dark text within the card.

BackgroundTint (a common response) is api 21+.
