In Appearance > Main Wavebox Window, click on the dropdown menu.

First, let's select 'Use the current Group color' and close Settings.

Click on each Groups to see the changes in background color. Lovely!

It's very satisfying!

To change the color, right-click on the Group icon and select a different color.

Let's head back to Settings.

Click the palette icon to customize the gradient opacity.

Drag the slider for a darker or lighter shade.

This time we'll chose the Space color.

Switch between Spaces to see the color change.

Right-click on a Spacce icon to select a different color.

Each Space can have a different color, to help you stay organized.

You can use any of the pre-selected colors.

Or click the palette icon to choose a custom color.

Choose a custom color from the picker.

Space colors are partocularly helpful when the webdock is in List Layout. Choose Webdock layout from the Settings menu.

Choose List.

Confirm you want to switch to list Layout.

When in List Layout, your spaces are hidden, so the color helps with navigation.

In this example, the color tells us which space the group is in.

Very useful if you have lots of Groups in each Space, but prefer them all in one long list.
