PreciseFP allows you to change the design of a template by selecting one of five themes. You are also able to select the main highlight color that will be used with the select theme.
To select the theme you wish to use, click the “template theme” button located on the top-right corner of the template editor.
To select a custom highlight color for your theme, select the last color circle on the right. That will open a color selection panel where you can select any color from the spectrum.
