Web night mode with a click

Put the web in night mode with a click. Or dawn. Or dusk. Adapt your web experience by changing the color the webpage is presented in.


Colorum Safari app extension

Colorum is a simple extension that let you overrule the colors used on a webpage and instead pick a color combination from a collection of predefined themes. Original color themes: Dusk, Night, Dawn and Noon.


The themes can also be activated by the contextual pop-up menu, reachable by ctrl-mousebutton or ”right-click”. And of course Colorum supports Mojave’s new Dark Mode.

(Be aware that applied color theme will currently only affect current webpage. If you change page the colors will be reset.)

Please contact us if you have questions or would like to see other themes!
