Color theory is important as heck to learn. Tip number one: Complimentary colors. Typically, colors on the opposite side of the hue wheel compliment each other. Blue/yellow is pretty widely known as one of the more aesthetically pleasing combinations out there which is why, now that you know about that, you'll end up seeing it in almost every movie out there. Scenes empty of any color other than shades of blue and yellow. That'll play into your photography through location/wardrobe. If you're shooting in an area with plenty of warm tones (like this set), using a cooler wardrobe will help balance that out and give you a visually pleasing palette to start with!
