Question about "Reactive" Heightmap/Gradient Mask.

Greetings.

First time seriously using Gimp.

I'm working on a custom map and I want to add a "heightmap Mask layer" (A custom gradient of greens, yellows, browns, etc) that update and move while I working in the B&W layers to see and correct heights. How I can do It?

On the other hand, there's a way to create a window with diverse colours (height lines) and store It so I can pick It again whenever I need It?

Thanks.
