Woah now, let's not get testy! Remember, you are basically asking for somebody to do free work for you...
Are you referring to the difference of the actual site versus the screenshot of the Deep Blue theme? If so, then yes, I guess I see a few differences, such as a different typeface and colors, but other than that, I think it's pretty close. Is that what you are trying to get at?
If so, you can either go into the theme files themselves and edit them (in the case of this theme, which is advanced, you will want to edit style.php, but be careful and make sure you know PHP), but actually I took a look at it, and you can change the colors and font yourself by going to Design > Current Theme Options after having activated Deep Blue to change it. Nice!
We'd love to help you, but please remember that you are getting free help, and if people are confused, maybe you could take the time to explain yourself more fully, include more details. Let us know if we are on the right track.
