Bob, you just demonstrated that you do not understand anti-aliasing:

"Anyone have a good idea on what color background will prevent or reduce the anti-aliasing effect?"

Do a bit of basic research. Educate yourself. The book I suggested, Creating Killer Web Sites is a start. It's a classic.

To me the tiny yellow shadow on the letters in the words Silicon Investor are practically invisible. Much ado about nothing. I happen to like the gray background a lot.

Bob, didn't mean to snipe without also giving the solution. Had to take a phone call.

Yes, there is a color background that will prevent or reduce the anti-aliasing effect: the original color. Butterscotch.

Anti-aliasing is a mathematical function performed at the edges of an area of color against a background color. It modifies the pixels at the edges to "blend" the two colors. The exact placement of the pixels, as well as the color values, are calculated in such a way as to minimize the perception of a "stairstep" effect along the edges. The eye will ignore the stairstep if the transition is eased with shading. The end result is a perceived (but not actual) increase in resolution.

When you changed the background color, the original anti-aliasing of blue-against-butterscotch was left untouched. Various pixels around the edges of the letters, in varying shades of blue-to-butterscotch were left there.

An experienced artist might be able to go in and mess with the individual pixels around the edges to come up with a pleasing effect. That is an emergency, stop-gap, inexact method, though.

The right way to do it would be to re-create the image from scratch, which, assuming that anti-aliasing is turned "on" in the drawing package, would anti-alias blue-against-grey, creating varying shades of blue-to-grey around the edges of the lettering.

I take it you didn't understand what anti-aliasing is. You can learn something every day, if you will take out the ear plugs.
