Go to the Toolset -> Settings page and click the Forms tab. In the Content Filter section, click the Select allowed HTML tags button. A dialog box for selecting allowed HTML tags will appear.

<span style="color:red">Lorem Ipsum</span>

When that form is submitted, the span tag will be filtered out and the following will be saved:
