The Problem: You have a lovely graphic, you save it for the web in the standard way, and the colors are way, way off.  Usually there is extra purple.  You scour the web and alter setting after setting in PhotoShop, all to no avail.

The Cause: It’s not Photoshop problem.  For whatever reason the default image previewer uses different color settings than Adobe Photoshop, and this results in a different looking image.

The Solution: Just ignore it.  The colors are only different in the preview, not in the final product.
