Why is the line changing from blue to magenta when changing layer?

See video:

The copied path was originally magenta... I changed it to blue.. then when moving to another layer, it is changing back go magenta visually, even though the property still shows blue.

I tried to upload the file, but the forum is telling me that my adobe illustrator (.ai) file: "

• The attachment's blue to magenta.ai content type (application/postscript) does not match its file extension and has been removed."

There is an appearance applied to that layer. Double-click 'Layer' in the appearance panel to view it:

Thanks, @Doug A Roberts --- didn't even know that was possible!

Thanks!

The appearance on the layer ... you probably haven't assigned that deliberately. So it has either happened because of picking up something with the eyedropper or via a graphic style or you have used the target symbol: https://youtu.be/jMDpnI5i7M0
