In map design, the choice of color scheme is dependent on the basemap. If you have a light basemap, most people will interpret dark colors to mean “more” and light colors to mean “less”. If you have a dark basemap, the opposite is true. The video below shows examples of designing with light and dark color schemes in ArcGIS Online and ArcGIS Pro.

Takeaways:

  • If you’re using a light basemap, dark colors will stand out more and so appear to mean “more”.
  • If you’re using a dark basemap, light colors will stand out more and so appear to mean “more”.
  • You can flip color schemes to control which end equates to more and which equates to less.
  • The subject of your map can sometimes override these rules.
  • In ArcGIS Online, you can search for color schemes designed specifically for light or dark basemaps.
  • If you’re struggling to find the right color scheme, try changing the basemap.
  • Colors all look different against different backgrounds.

There are a lot of other considerations that go into designing choropleth maps. You can learn about some of them in this related video: Configure a choropleth map.

You can follow along with the map in ArcGIS Online or in ArcGIS Pro.
