Geometry map color cover

Troubleshooting General Help
1

hi~
I want to create a 2d map using a quad with the map image texture.
And I want to let the different part of the map fill with different color.
For example, I create some countries and different countries have different territories, And that territories have different color cover.
So far, I tried to change the color of the material of the quad geom but it only changes the whole geom 's color.
So I don’t know how to do it.
Can somebody give advice to me? Thank you very much.

This is mentioned in one of the first beginner tutorials of JME, unless I am misunderstanding…

/** A simple textured cube – in good MIP map quality. */
Box cube1Mesh = new Box( 1f,1f,1f);
Geometry cube1Geo = new Geometry(“My Textured Box”, cube1Mesh);
cube1Geo.setLocalTranslation(new Vector3f(-3f,1.1f,0f));
Material cube1Mat = new Material(assetManager,
“Common/MatDefs/Misc/Unshaded.j3md”);
Texture cube1Tex = assetManager.loadTexture(
“Interface/Logo/Monkey.jpg”);
cube1Mat.setTexture(“ColorMap”, cube1Tex);
cube1Geo.setMaterial(cube1Mat);
rootNode.attachChild(cube1Geo);

sorry, maybe I have spoken unclearly.
My question is that I created a quad geometry as I set the quad geometry to be my background image with a image(map) material(already done)
Then I want to separate the quad geom(map) to many parts and to be cover by colors(each country has one map color).

So… make a picture of your map and put it on the quad as a texture…

Or do you want something to happen when you click on a country maybe?
