SUMMARY At first, I wondered what's the new exclamation mark icon in my tray. When I clicked it, I saw its the night color tray icon, but it took quite some time to realize that it probably should be a light bulb. I think the icon should be improved. I am not sure how. Maybe adding a hint of screw? Another thought would be if a light bulb resembles current light at all. Many modern LED lights have other shapes. redshift-gtk works around the issue by using color and using red / blue to indicate if it is active is nice. But I guess Oxygen requires using black&white for tray icons, so there needs to be another thing to make the shape easier to recognize.
