coloring edges in sketchup

the sketchup help files are "sketchy" about this
I have a group of edges I'm using to represent snaplines in one of my class projects, and I would like them to be red.
I've done this before, but cannot seem to redo.
Can someone help me here?
thanks,
Mark.

Go to your 'styles' palette.
Select 'Edit'.
Click on the hollow / wire frame box (Edges).
Look down at the bottom: 'Color'
Select 'by material'.



Select a line.
Right click for Entity info.
Click the grayed out box / materials.
Choose or edit a color.

ten thousand thanks,
I just don't do this often enough, I'll save your post in my sketchup info folder...
