Help please... Should be simple lol

I am using the Royal_Preloader that came with the Dot Template I downloaded and can’t find where to change the background colour from Black to the colour I want. It is really annoying me now lol. If anyone has experience with this I would really like the advice. I look forward to hearing from you. Thanks in advance.
