Dimmer Contour Lines Overlay
Replaces the blindingly bright white background of the contour lines overlay screen with a dimmer grey. There doesn’t seem to be a way to remove the shading all together; all I could do was change the colour, so I decided just to make it a neutral grey (0.5, 0.5, 0.5). Strangely, the background colours of the other overlays don’t seem to be modifiable (at least, not obviously).
