How do I change my Edge Loop color from yellow to blue? I'm just starting out on Blender and I'm finding the yellow edge loops on the grey object color a bit harsh on the eyes. 
How do I change this so when I use the edge loop shortcut CTRL R, the preview edge loop will be whatever color I decide on?
