Changing Background Color

Rainbow Changing Background Color

First time using GIMP. Amazing product! More amazing that it is free. Kudos to all who have invested their time and effort. Following the directions here:

Using, "Color to Alpha," I tried to select the background of my .jpg image. The background is white, the picture (logo) portion is silver. Because of the closeness in color, when I select white, the software selects the entire image to become alpha (transparent).

When I select the color of the picture, silver, I am able to select just the logo portion. How can I take the logo portion, which is now converted to transparent, and give it a black or transparent background, and then return the logo back to its former color silver. The logo is perfect, it is just that I recently switched my site from a white header to a black header and the image has a white background, so that does not look good.

I hope I am being clear. Can anyone help? Effectively, I am doing the opposite of what I want to do.
