Here is an example of "cool" lighting. Blues are used to relax the guests. They can also be used to convey an icey feel for winter months. The blues are mixed with white lights in the picture to the right.
Here reds and oranges are used in the color pallette. But the photo to the left uses ambers which is very flattering for complexions. the photo on the right uses whites and reds to convey a tone of excitement. Pinks can also be used for that feeling as well.
This last picture by Laura Novak is an example of more amber lighting mixed with candlelight. The leafs in the center are examples of gobo lighting, which simply means a pattern. You can use your names, monogram, pretty much anything.
