How do I cycle a specfic section of a palette?

Is there any way to cycle a section of a palette?

I’m trying to make quick & simple water for a little game, but can’t figure out if there’s a way to change the palette on one frame to the next.

Is it possible to do this? If so, how?

Thanks!

This is not currently possible, so you’ll have to recolour the water in each frame.

The feature to allow per-frame palettes (allowing for colour cycling) is planned for 1.3, according to this thread: Color cycling effect?
