Oh, Statamic is a BYOFE (Bring Your Own Front End). Out of the box, it gives you a templating language that you can take or leave. You are 100% responsible for all HTML, CSS, and whatever JS you feel like bringing to the table. There's no handling of colors or anything to override, because that's all on you. SSG is a mode it has, it's not the default.
It's pretty close to being a flat-file ExpressionEngine, if that helps.
