Perhaps you could post links to your input and output images and also identify your IM version and platform.
Your tinting is likely affecting anti-aliased pixels differently, some more than others, so you lose the effectiveness of the anti-aliasing from the resize.

We need to see your input and output images. Put them on some hosting service such a DropBox (no need to download there software to use via web) and post the link.
By the way "Jazzy" is not a word! You may know what you mean, but I have no idea what you mean!

Anthony,
His pictures were there for a while. Not sure why they disappeared, but they were posted as one picture and not separate. What appears to be happening is that his coloring is affecting the anti-aliased pixels from a resize in a way that loses the anti-aliased smoothing and so the edges are jaggy (what he means by jazzy, which is actually a word from the root jazz, e.g. music, but not relevant here)
