Is it possible to recolor a lottie animation programmatically?

Question

If I have a lottie animation in the form of a json file, is there a way to recolor it in code or even within the json itself?

(To be clear, I hope there's a way to do it without involving After Effects. For instance if I decide to change my app's primary color, the whole app will change except the animation unless there's a way to do that.)

There is another thread on this topic with the same approach but a bit simplified: How to add a color overlay to an animation in Lottie?

Here's directly an example (Kotlin):

        yourLottieAnimation.addValueCallback(
        KeyPath("whatever_keypath", "**"),
        LottieProperty.COLOR_FILTER
    ) {
        PorterDuffColorFilter(
            Color.CYAN,
            PorterDuff.Mode.SRC_ATOP
        )
    }

You can find the names of the keypaths also in the Lottie editor.
