Ken Rockwell said in his review of this camera, "Blah color rendition, much duller than Canon, Nikon or iPhone 5. It's optimized and great for people photos, but too dull for photos of things. The X-E1 excels in crappy light, but its colors don't look very good in good light. Even when set to HIGH color, it is subdued and doesn't respond well to adding saturation later."
From these images and others that I saw elsewhere so far, I can see what he meant.
