Highlight the Layer in the Layers Panel and from the Layer Panel menu choose "Options for Layer X". That will allow you to change the highlight color.
You can also double-click the layer thumbnail to bring up the Layer Options.
I have created a file with several layers, and each layer has several sublayers, When I open the document, all the parent layers are expanded in the layers panel, making a very long list. I would like to have the layer panel display only the parent layers at the start. Is there a way to set this up?
You should post a new topic if you have a new question.
In addition, your question ahs been covered many times. But I realize the search function here leaves something to be desired.
Layers, containing sublayers, will always expand when a file is opened. It's been a problem for a while and there is no fix.
I'm on Barb's side. The Yellow layer color is useless. I'd like to get rid of that color (Layer 5) permanently. Her question wasn't answered except for the temporary fix. Is there a way to remove this color forever?
No, it can’t be removed permanently. Nor should it be. Yellow can be very useful when working on dark background colours.
I only wish smart guide texts could be made to work on dark backgrounds too.
