how to turn off colorbar in "3 column" theme

[aramazd88]

folks, I like to turn off colorbar in my template no matter what I do I am not able to. since my banner/Logo needs to be large and visible these two graphic bars do not allow it( not fully visible).
i am using "3 column" theme layout and also this is where you will see TEXT-A ( in page layout)

You can add the following CSS code onto all pages (such as in the header field).
<style type="text/css">#colorbar {display: none;}</style>
