# Solarized Dark Theme for Firefox Reader View Firefox Reader View has a limited, non-extendable set of themes, which doesn't include [Solarized](https://ethanschoonover.com/solarized/) Dark. Which is unfortunate because I put Solarized Dark on everything I can. But if you want to spend 3 minutes, you can set the right palette in the Custom Theme tab. ![Screenshot](/12_articles/images/12-65-screenshot.png) 1. For each of the four colors in the palette, click on the ✏️ button to open the color picker pop-up. 2. Switch to the "Color Sliders" tab. 3. In the sliders dropdown, choose "RGB Sliders." 4. For the "Background," enter "Hex Color #" `002b36`. 5. For the "Text," "Visited Links," and "Unvisited Links," put `839496`. 6. Leave "Highlighter for read aloud" at its default value. And Bob's your uncle.
