Changing Themes in Arc
Customising your Arc browser theme is quite a straightforward process, regardless of the operating system. Here’s how to get started:
Step 1: Hover over your space name and then head to Edit > Edit theme colour.

Step 2: Here are some options that you will see when you open the colour picker:

- Dark and light modes: Toggle between these two options to suit your preference and reduce your eye strain.
- Predefined colours: Choose from a selection of present colours for quick customisation.
- Luminosity control: Adjust the intensity of your chosen colour to fine-tune the visual impact.
- Colour region selection: Modify specific areas of the browser interface with your preferred colour.
Play with the above options will you get the right colour for your Arc browser theme. If you are using Arc on a MacBook, you will get two extra options:
- Gradient creation: To combine multiple colours to create stunning gradient themes.
- Graininess dial: To add texture to your theme for a unique visual effect.

Windows-specific background options in Arc
Arc has some Windows-specific customisation features that you can use to further enhance your browser experience. Here’s how to access and use it:
Step 1: Click on the Arc icon at the top left of the screen and then select Settings.

Step 2: Next, under General, head to Windows backdrop and select from these two options: Mica or Acrylic.

Mica displays your Windows wallpaper behind the Arc window and hides windows underneath Arc for a cleaner look. Also, this option uses fewer system resources.
On the other hand, Acrylic provides a transparent effect, showing all windows beneath the Arc browser. It offers a more immersive visual experience when compared to Mica. However, it may use more system resources and is not suitable for older computers.
You can consider the following points when choosing between Mica and Acrylic:
- System resources: If you’re running Arc on a less powerful machine, Mica might be a better choice for optimal performance.
- Visual preference: Acrylic provides a more dynamic and integrated look, while Mica offers a cleaner, more focused interface.
- Multitasking needs: Acrylic allows you to see windows behind Arc, which can be useful in some situations.
