How come Vivaldi picks nice accent colors for most websites, but on my site (which is white, black and blue) it goes with the default red, which clashes horribly with the color scheme.

How do I control the accent color of Vivaldi?

Answer 1

While I haven't come across any official statement so far, it seems that Vivaldi determines the accent colour mainly from a site’s favicon. However, the HTML standard also specifies a meta element named theme-color that can be used „to customize the display of the page or of the surrounding user interface”, and Vivaldi respects this tag when it is present in the source code. Of course, this meta tag will also affect other browsers with similar features, such as Chrome for Android.
