    I’ve looked all throughout the documentation, and google searches. Is there a way to script changing color of layers. I’m building a script that parents a null to another layer, then depending on that layers color, the null will be a specified color. Not looking for labels either, but color of an actual layer.

    The only thing I can think of would be to do a replaceWithSolid() on the null’s source and specify the color you want, like this:

    var myNull = app.project.activeItem.layer(1);

    var myFootage = myNull.source;

    myFootage.replaceWithSolid([1,0,0],myFootage.name,myFootage.width,myFootage.height,myFootage.pixelAspect);

    Hi Dan,

    Thank you! This is a very clever solution to changing the the color of the icon on the null layer. Which would be an amazing alternative. But if possible is there a way to actually change color of the layers themselves on the timeline?

    I think you do have to go after the color of the solidsource for the null (rather than the color of the layer itself), but it’s not as tricky as I thought. This should work:

    var myNull = app.project.activeItem.layer(1);

    myNull.source.mainSource.color = [1,1,0];

    I think what you need is to change the color of the layer in the timeline is to just set the label:

    app.project.activeItem.layer(index).label = 8; // takes an integer from 0-16 - 0=no label

    You can choose one of the preset color-labels as setup in your preferences, but you cannot change those presets via scripting.

    Thank you both for your brilliant solutions, this definitely places me at the end of the creating the script. For some reason I thought the label method, only applied to layer markers. Both these methods make it a lot more efficient in creating color hierarchies.
