我在使用相同纹理生成随机颜色的武器时遇到了同样的问题.

I faced the same Issue for generating weapon with random colors using the same texture.

所以我写了这个.
基本上，我会为您要编辑的纹理制作像素图.

So I wrote this.
Basically I make a pixmap of the texture you want to edit.

然后你迭代所有的像素，在迭代的同时我检查某些颜色，这些颜色是纹理的特定部分.(我建议使用不同深浅的灰色，因为 RGB 是相同的)

然后，当它位于需要更改颜色的像素上时，我使用颜色选择器方法为这些像素组获取颜色，该方法基本上是随机的，从预制颜色数组中获取颜色，
然后将该特定像素更改为新颜色.

Then you iterate over all of the pixels, while iterating I check for certain colors which are a part specific part of the texture. (I suggest using different shades of gray since the RGB is the same)

Then when it is on a pixel where the color needs to be changed I grab a color for those pixel groups using a color picker method which is basically random which gets a color from a prefabbed color array,
and then changes that specific pixel to the new color.

/**

 */
private static Texture genTexture(String texturename, int colorBlade,
        int colorEdge, int colorAffinity, int colorGrip, int colorExtra) {
    Texture tex = Game.res.getTexture(texturename);

    TextureData textureData = tex.getTextureData();
    textureData.prepare();

    Color tintBlade = chooseColor(mainColors);
    Color tintEdge = new Color(tintBlade.r + 0.1f, tintBlade.g + 0.1f,
            tintBlade.b + 0.1f, 1);

    Color tintAffinity = chooseColor(affinityColors);
    Color tintGrip;
    Color tintExtra = chooseColor(extraColors);

    boolean colorsAreSet = false;

    do {
        tintGrip = chooseColor(mainColors);

        if (tintAffinity != tintBlade && tintAffinity != tintGrip
                && tintGrip != tintBlade) {
            colorsAreSet = true;
        }
    } while (!colorsAreSet);

    Pixmap pixmap = tex.getTextureData().consumePixmap();

    for (int y = 0; y < pixmap.getHeight(); y++) {
        for (int x = 0; x < pixmap.getWidth(); x++) {

            Color color = new Color();
            Color.rgba8888ToColor(color, pixmap.getPixel(x, y));
            int colorInt[] = getColorFromHex(color);

            if (colorInt[0] == colorBlade && colorInt[1] == colorBlade
                    && colorInt[2] == colorBlade) {
                pixmap.setColor(tintBlade);
                pixmap.fillRectangle(x, y, 1, 1);
            } else if (colorInt[0] == colorEdge && colorInt[1] == colorEdge
                    && colorInt[2] == colorEdge) {
                pixmap.setColor(tintEdge);
                pixmap.fillRectangle(x, y, 1, 1);
            } else if (colorInt[0] == colorAffinity
                    && colorInt[1] == colorAffinity
                    && colorInt[2] == colorAffinity) {
                pixmap.setColor(tintAffinity);
                pixmap.fillRectangle(x, y, 1, 1);
            } else if (colorInt[0] == colorGrip && colorInt[1] == colorGrip
                    && colorInt[2] == colorGrip) {
                pixmap.setColor(tintGrip);
                pixmap.fillRectangle(x, y, 1, 1);
            }
            else if (colorInt[0] == colorExtra && colorInt[1] == colorExtra
                && colorInt[2] == colorExtra) {
            pixmap.setColor(tintExtra);
            pixmap.fillRectangle(x, y, 1, 1);
            }
        }
    }

    tex = new Texture(pixmap);
    textureData.disposePixmap();
    pixmap.dispose();

    return tex;
}

我希望这会有所帮助.
