PNG background color matching issues

I'm having some issues with the background color of my header image matching the background color of my website. My CSS defines the background color of the header as #34301D, I've gone into Photoshop and filled the background color of my logo as the same. I then do a Save for Web in photoshop and create header.png as PNG 24. The background color of the image appear fine in Safari, Firefox begins to to show a slight differentiation, then when I checked on IE6 it looks like 2 completely different colors.

Alternatively is there a way that I'm just not aware of to force IE to support alpha transparency?

what about using a single pixel image with the same color/format as your header image as the background "color"?

I considered that too, after consulting my old friend google there are a few hacks around to make IE5.5 and newer compliant with PNGs.

I'm trying to implement this one right now, but I'm getting mixed results.

I'll report back if I get it working properly.
