The logo design and colors you choose for your business' brand have an impact on the clients your company is trying to attract.
The colors and designs you choose for your logo and website should be appropriate for your industry and the clientele you serve.
For example (as shown in the screenshot above - from http://jmd-law.ca), you'll notice the navy blue color of the navigation bar and in the "JD" logo design. Navy blue (or a varied shade of navy blue) is a color that evokes business professionalism and respect. This comes from a serious business and/or legal professional setting where most who work in this industry wear navy blue suits and ties.
It's an appropriate color for the legal industry where potential clients will expect the law firm to take them seriously, and those potential clients want to hire respected professionals.
The "JD" logo is nice. It has a more unique look and feel than simply having the letters "J" and "D" written out in a particular font. It can be difficult to design a well-crafted logo when the business name is the name of the founder. The logo allows you to follow through each letter and with that intertwined shapes of the lines that make up the letters there is movement which draws your eye back to the beginning of the logo as you read the letter "J" to the letter "D" from left to right. I also like the repeated angle at the start of the letter "J" and at the end of the letter "D."
Here's another example (http://meadowlandsortho.com). This site is for an orthodontics office. The patients are most likely teen and pre-teen kids, as that's often the age in life when permanent teeth are all in and may need some help to ensure their align well. Parents of those kids are the other audience for this site.
While it's not necessarily fun to have braces this company chose green as a the color in their logo and website, which I believe is a good choice. Green is inviting and calm. This is helpful most kids who have to get braces are apprehensive and anxious about it. Green is also often associated with health and growth.
The logo is nicely done. It incorporates the green color and depicts an image of a stylized tooth with a brace in black running across it. It also looks a bit like a tree growing out of a meadow -- a truly nice design that is visually descriptive and metaphoric. It is fitting for the Meadowlands Orthodontics name.
