How to overlay color on texture in libgdx?

Question

I'm using texture and textureAtlas in libgdx. This textures loads images of white circle.

How can I overlay its color with another color? Or maybe their is another approach for this?

private final static TextureAtlas textureAtlas = new TextureAtlas(Gdx.files.internal("spritesheet.atlas"));
private final static TextureAtlas.AtlasRegion texture = textureAtlas.findRegion("Bubble.001");

EDIT: As I said I have a white circle and I want to make it red (without the need for another image with a red circle)

Answer 1

You can use the lerp method in Color class.

actor.setColor(Color.WHITE.cpy().lerp(tintingColor, .5f));

lerp changes your Color object, so use the cpy command before it to preserve the original color. In this case I use WHITE as my original color, which preserves the color of your Actor's texture. lerp will overlay the tintingColor with a strength of 50% in this case.
