**Post:**

Hi Team,

I am applying colors to nodes using `viewer.model.setNodesColors()` like this:

```auto
const colorMap = new Map();

for (const nodeId of nodeIds) {
  colorMap.set(nodeId, new Communicator.Color(255, 0, 0));
}

await viewer.model.setNodesColors(colorMap);

```

This works correctly and applies the color to the nodes.

Later, I want to **reset the nodes back to their original model colors**. However, if I assign another color like:

```auto
colorMap.set(nodeId, new Communicator.Color(255,255,255));

```

Not working :- not changing the node color to white

Not working:- not restoring the original material color.

What is the correct way to **remove the color override applied by `setNodesColors()` and restore the node’s original color**?

Would passing `null` for the color value be the recommended approach, for example:

```auto
const resetMap = new Map();
for (const nodeId of nodeIds) {
  resetMap.set(nodeId, null);
}

await viewer.model.setNodesColors(resetMap);

```

Is this the correct pattern to restore the original colors?

Also, does this behavior differ for nodes that have **texture mapping** applied?

current version - Hoops Version: 2023\_SP1 this is not working as well. await viewer.model.resetNodesColor();

Thanks!

I would expect this call to work:  
`await hwv.model.resetNodesColor();`

As a quick test, I ran your code snippet in the default Web Viewer:
