z = zb_zone(zb_region, point = zb_region_cent)
zb_view(z, palette = "hcl")
zb_view(z, palette = "rings")
zb_view(z, palette = "dartboard")



Personally, I like rings the most. It is effective, and the map is still visible. It feels like wearing sunglasses.
The hcl palette has the advantage that each zone has a distinct color.
The dartboard is mostly for fun.
