If you're ever seen portraits shot somewhere like an arcade or next to a neon sign, you know they offer a neat look full of washes of color that envelop the model. If you don't have access to such lighting, this great video will show you how to recreate the effect at home.
Coming to you from Gab Loste, this fun video shows you how to recreate the neon light effect that's popular in portraiture these days at home, using nothing but your television and some basic equipment. As the video mentions, you'll need a prism of some sort to help create the effect; I personally recommend any of the standard classroom versions you can get on Amazon. I've had one for years, and the long length makes it easy to hold and position as needed in front of the lens. Remember, since you're likely using slower shutter speeds, you can also grab a tripod (just make sure your model stays still as well). Also, since your model will be very close to the television because of the limited light, be sure to use graphics that are diffuse; if they're too sharp and defined, the effect won't be what you want.
