Consistency is important. Once you have decided on a logo design and color scheme for your business, it's important to keep everything in the same colors. Also, you should incorporate your logo or elements of your logo on anything you have your graphic artist create for you. Printing and Internet for example. Not only does this make everything look great together when your customers see them, but it also creates an impression in their minds. Any time they see your logo, colors, graphic elements, etc., they recognize that it's "you". Think about other businesses that you see every day that are recognizable just by their color and/or logo. Apple, Coke, Sprint, AT&T, Nike, Chevrolet, etc. Those logos are recognizable any where.
Also, your logo needs to be simple to read or see from any distance or size. If you have lots of busy pieces and elements in your design, they tend to just blend together at smaller sizes or at far distances.
