I want a selection that I made to be filled simply completely with one color. I used the fill tool and changed tolerance to 100%. However, some dark pixels have alpha in them and they are not being overwritten. How can I simply make every pixel of the selection white, with no alpha?

Welcome to the forums @Rob_87
I’ve tried to replicate what you are getting but cannot (see attached video).
Would you be able to supply the document (or a cropped version) so we can experiment?

Note: In your first image, the Flood Fill won’t affect the pixels outside of the selection so you could be missing some pixels from your selection anyway; you need to make sure that the selection covers all of the pixels you want to affect.

Also, note that the selected area, as shown by the marching ants is only approximate. The ants include pixels that are at least 50% selected, but there may be pixels outside marching ants that are partially selected.

Perhaps that helps explain what you are seeing.
