Anyone know how to change the color of the lines that go across the screen, or better yet a link to the theme with different colors.

I need to change the line colors to go with my themes color scheme. I am able to change the color easy enough, but not being very experienced with photoshop I cant get the same effects. When i change the color it just makes the whole line a solid color, and doesnt keep the gradient effects.

Any help would be appreciated.
