There is no default specified by T35 but in HTML, there are some things that it assumes if you don't specify. One is that if you don't specify a font, it uses Times New Roman (or other font set by your Operating System/browser's theme in some cases). The color works the same way. Usually defaults to black, but if you save a different theme in your operating system or browser, that will manage what displays. In short, if you REALLY want your text to be Times New Roman, black, I would debug the issue with the other text on the site. If you are okay with it using whatever fonts the user has set up on their system then don't worry about coding that. Hope that answers your question :-)
