Abstract

Der Dunkelmodus (engl.: dark mode) ist eine immer häufiger verwendete Gestaltungsoption, bei der ein dunkler Bildschirm-Hintergrund mit hellen Text- und Graphikelementen verwendet wird. Diese Option gewinnt auch wachsende Bedeutung für die Gestaltung von Bildschirmkarten. In diesem Beitrag wird der Vermutung nachgegangen, dass bei der Nutzung von Choroplethenkarten analog zum „dark-is-more bias“ bei hellen Hintergründen (d. h., dass dunkle Farben größere Attributwerte repräsentieren) ein „light-is-more bias“ im Dunkelmodus gilt. Die Ergebnisse einer Online-Studie mit 214 Personen belegen jedoch, dass weiterhin der dark-is-more bias auch für den Dunkelmodus die eindeutig die häufigste Anwendung findet. Diese Häufigkeit fällt gegenüber dem Hellmodus etwas geringer aus, ist abhängig vom gewählten Farbschema für den Dunkelmodus und variiert je nach Nutzerexpertise. Die Studienergebnisse erlauben auch generelle Gestaltungsempfehlungen für künftige Dunkelmodus-Farbschemata für Karten.

N2 - Dark mode is an increasingly common design option in which a dark screen background is used with light-coloured text and graphic elements. This option is, therefore, also relevant for the design of screen maps. This article examines the question of whether a “light-is-more bias” also applies in dark mode for the display of choropleth maps, analogous to the “dark-is-more bias” with light backgrounds (i.e. that dark colours are associated with greater attribute values). However, the results of an online study with 214 people show that the dark-is-more bias is still clearly the most frequently used strategy. This frequency is slightly lower compared to the light mode, and it is depending on the specific colour scheme for the dark mode and on user’s expertise. The study results also allow general design recommendations for dark-mode colour schemes for maps.
