Have you noticed the amount of maps with black or dark backgrounds that you see online these days!? It is a common trend to use light-on-dark to create a striking visual hierarchy and most of the maps that go viral tend to have adopted this style. I’m sure that has something to do with the aesthetic appeal and the initial impact of these maps. Using a dark background leaves room for many light colours which can create great contrast for any overlays that immediately become the maps focal feature as they often appear to glow.
Here are some examples:
The majority of traditional maps use white (or similar) as the background colour and this can be largely attributed to the distribution mechanism which would usually be paper. The majority of paper is white and it also brings cost savings with regard to ink usage – it wouldn’t be wise to smother a sheet of white paper with dark ink!
With modern mapping technologies and the internet as the main method for sharing maps, any print concerns that restricted design decisions in the past are no longer an issue. Many maps these days will never be printed, just pored over on PC screens and mobile devices.
There is something cool, aesthetically pleasing and eye-catching about dark maps.
It may just be that this bold technique portrays a certain element of rebellion – a refreshing break from tradition.
