Unexpected Blogger photo conversion

There appears to be something odd going on with photos when uploaded via the Blogger interface. Normally, Blogger automatically resizes the photo, but as far as I knew, it didn't alter anything else about the photo. Today I discovered something odd is occurring with the color of the photos. I have no idea if it's a new development or whether I just happened to notice it now.

Here's an example. This first photo is what my original photo looked like. The second photo is how it appears if I use Blogger's photo upload feature.



Feel free to click on the photos to see even large versions. The color changes are much more obvious with the full-sized version. Notice the coloring of the second photo is washed out. It's somewhat subtle, but it bugs me enough that I'm now going to start resizing photos myself so I know exactly what will appear on this blog.
