As you may have noticed from the logo at top, I'm having difficulty color matching. It's strange because the colors match up in photoshop (confirmed by the color picker tool) but appear to change after saving to .png. Since png is supposed to be lossless compression, I'm confused. Any ideas?

Make the image background transparent.

And yes, I had that problem with pngs as well. Something to do with safe mode in browser rendering for shitty old ass monitors if I remember correctly.

what i mean is... if your css code for the title is something like #ff6600 (orange, like mine was) and then you go into photoshop and do the same thing... for some reason the browser doesn't render the color as the png in photoshop does.

you have two options (other than transparent bgnd)... used black. every black matches well enough.... even browsers don't screw up #000000, OR make a 1 pixel wide by 100 (or whatever tall) png of the background color and code it to repeat horizontally, and then insert your header image on top. that will match as well.

Good advice. Thanks. Transparent background seems to have worked.
