When you sign into your Passion.io account for the first time, you can define how your app should look like by selecting pre-defined templates. To make changes in your chosen template:
1. On your App Builder dashboard, click the Theme Tab (the one with the pain palette icon) located on the side panel.
2. Choose any of the ready-made palettes.
If you want a bit of customization, go to Customize Colors, click on the color you want to change and drag your mouse to your chosen color.
You can also put in different colors by typing in the hex code. To get the hex code of a color, go to Google search bar and type in hex color picker.
3. Drag your mouse around the Colour picker and it will show the hex code, located below the slider.
4. Input the hex code to change the color on your templates.
