Light fixtures project washes of light adding color, warmth, and depth complementing the colors you are using for your decor. Uplighting looks fantastic in photos and is a great base layer for transforming the event space.
Generally, you need a light for every 10ft - 20ft of wall length depending on the overall look that you want to achieve. Uplighting can come in any color of the rainbow for your event. Amber, blues, purples, teals, reds, yellows all look really nice for uplighting. Oddly enough colors like green can be unflattering when used exclusively and colors like black and brown can't be achieved. Silvers can be done as whites, a textured light, or in conjunction with a pipe and drape.
You can do a solid color throughout the room, multiple colors or have the lights change at different points during the evening. Priced at $35 per light.
