A dynamic Firefox theme that changes the theme to the current website's "primary" color. Available in Firefox Add-ons.
Order of precedence for determining the color:
- The meta theme-color element (except for pure white)
- The dominant color in the favicon, as determined by node-vibrant
- White as a fallback
Color Tailor was originally created for the Firefox Quantum Extensions Challenge. I wrote a blog post detailing my experience.
Install Color Tailor from the Add-ons page. Firefox 63 and above is required.
Color Tailor was inspired by an iTunes feature that would change UI colors on the fly to match album covers.
Chrome on Android does a similar thing with the toolbar color, and there is an open issue to do the same for Firefox.
Vivaldi has this feature built-in.
- Chromatastic: continuously cycles through colors
- Containers Theme: changes the theme color to match the active container tab
- Picture Paint: changes the theme to match the color palette of the current National Geographic Photo of the Day
- Quantum Lights: Firefox Quantum palette-inspired theme that changes based on the time of day
- Gradientus: also changes colors based on the time of day
