CSS Customization

I’m new to Syncfusion and am having trouble understanding how to override the CSS styling. For instance, I want to change the color of the button in SfUploader. I looked at the appearance setting on the website but where does this go? I can’t find the syncfusion css styles anywhere so I’m guessing they are in a dll somewhere. So am I supposed to create my own css file and import that? Also, it seems like a lot to simply change the color of a button for the uploader?
