You can change the color of an attachment with the slot's color:
Key Frames - Spine User Guide: Slot color

Clipping is not in 3.5 but it is in the latest 3.6 beta.
Settings - Spine User Guide: Version
Clipping doesn't have documentation yet, but you click a slot, then create a new clipping attachment which gives you a clipping polygon.

What do you mean by waves or ripples fading in and out though?
It doesn't sound like something clipping could be useful for.

Create a new Clipping by going to New > Clipping.
Clippings are stored on a slot like any other attachment.
Then go to Draw Order and move the Clipping to its start spot and set the End Slot under the properties.

Here's an example of how I use it in the updated Spineboy project.

Thank you!
And one more question, can I make a stroke for characters animation in Spine? Like in attachment:

Not automatically, and not in Spine editor.

It's not a Spine thing. It's more because in most game engines/frameworks, outlines are done by adding your own lower-level custom render commands. It's sort of specific to the graphics setup and graphics code of your game.
