About this pair
Mono Slate removes hue entirely. It runs from near‑black at the top through graphite to a steel highlight, with a soft horizontal grain that keeps it from looking like a flat fill on an OLED panel.
A neutral wallpaper is the practical choice when your icons already carry colour — a grey background lets a colourful app grid look deliberate instead of accidental. It is also the safest base if you change widget palettes often, since nothing you put on top of it will clash.
The grain matters more than it sounds. Pure grey gradients band badly on OLED screens, especially large ones at low brightness. Both files carry a small amount of noise specifically to prevent that, which is why they look clean at night on the inner display.
Works well with
- Colourful app icons
- People who change widget themes often
- Low-brightness night use
Setting it up
- Download both files above.
- Fold the phone closed, then Settings → Wallpaper → Add New Wallpaper → Photos and choose the cover file.
- Unfold and repeat with the inner file.
If it ends up cropped or zoomed, this is usually why.
