You can change the color theme of a fiscal from your desktop in Xena. You can have access to multiple fiscals. In the top right corner of every representation of a company, you can click on the menu icon.
In this menu, you find the color theme selector. You can choose from 14 different themes.
In this example, we picked the blue theme. Notice that the header and menu bar changes color. When inside that fiscal, this color will follow along. This way you can have different themes for your different fiscals.
