Hi @zyy1987,

We have a Sandcastle demo that demonstrates this functionality here: [Cesium Sandcastle](https://sandcastle.cesium.com/?src=3D%20Tiles%20Point%20Cloud%20Classification.html). In particular, this block of code is responsible to assigning points of the point cloud different colors depending on their `id`:

```auto
classificationTileset.style = new Cesium.Cesium3DTileStyle({
  color: {
    conditions: [
      ["${id} === 'roof1'", "color('#004FFF', 0.5)"],
      ["${id} === 'towerBottom1'", "color('#33BB66', 0.5)"],
      ["${id} === 'towerTop1'", "color('#0099AA', 0.5)"],
      ["${id} === 'roof2'", "color('#004FFF', 0.5)"],
      ["${id} === 'tower3'", "color('#FF8833', 0.5)"],
      ["${id} === 'tower4'", "color('#FFAA22', 0.5)"],
      ["true", "color('#FFFF00', 0.5)"],
    ],
  },
});

```

Let me know if you need further assistance!

Best,  
Janine
