I think you need to change either your color profiles or/and your proof setup.
Color profiles change the way we interpret the colors. For web images we don’t need that.

The proof setup is the way we see the outcome of the image. For example if you’re designing for print you’ll want the proof setup as a CMYK instead of RGB. To make shure no colors are being skewed for web images we need to change that as well.
