In HOOPS Communicator you can change the selection color using `Communicator.SelectionManager.setNodeSelectionColor` and `setNodeSelectionOutlineColor`. However, these API’s are limited to a single color for selection. If you want to use multiple colors to highlight objects, you can achieve this by bypassing the selectionManager and setting colors directly using `Communicator.Model.setNodesLineColor` and `setNodesColors`. When there is no selection, reset the color using `resetNodesColor`.

Be aware that setting colors directly will be slower and will generally cause a scene refresh vs utilizing the SelectionManager for highlighting.
