Jpegs display with few colors

This may have been caused by me honking around with the files outside of EF.

The view of my image files now display in EF as if they are in a limited color palette, even 256 colors.

How do I repair this?

How do they look in Preview? Have you tried restarting your Mac?

Universal Problem
Well, it is in every viewer. And it just happened in the last couple days.

Could it be a hardware failure? Is there a system setting that may have been toggled to 8 bit color?

I think Apple removed the setting for the number of colors, however there is an enhanced contrast setting in Universal Access that could cause a similar effect. Either way, you would see this globally (in the menu bar, desktop picture, etc.), not just in the image view.
