Google is still in the process of updating its apps and services with its new, more modern Material Design. While Google updated Search’s web interface a few days ago, it’s doing so again.
The cards used to feature solid colour headers on mobile. The update adds a pastel gradient instead.
So far, it looks like different colours visualize specific content. Notable people are highlighted with blue, books with purple, songs and videos with red and movies with orange.
In the Play Store, Google makes use of the same colours. However, different colours represent different media types than they do in Search. For example, with the Play Store, orange is tied to music, while with Search the colour represents movies.
The new Knowledge Graph search cards seem to be rolling out as a server-side update since they haven’t appeared on many phones yet, according to Android Police.
