    I’m wondering what is the best and most efficent way to set diffuse color for multiple objects programmatically.

    To be more precise:
    I got around 480-520 objects which are named unique. The all got the same material applied. After a certain user interaction I need to “group” these objects. Therefor I got an array with 4 different colors. These colors need to be applied to all the objects by their names. It is also necessary to apply the inital material after a certain user interaction.

    My current approach would be, to create 4 new materials (directly in js) with the different colors I need. And then apply each material to the appropriate object.
    When I dont need the colors anymore I would simply apply the intial material.

    Would this be the best way, or are there other approaches?

    For the moment I created a new material for each object. Works so far.
    Just not sure if this will make the scene slow at some point, when this function is executed several times.

    it’s ok to run this multiple times – it is a key to not perform heavy operations every frame

    You could also consider vertex color.
