How to fix this image?

Here are two images a picture taken with my K5.

The first one is RAW and processed in Aperture 3. The second is the embedded jpeg.

Notice how the colors on the embedded jpeg are so much better? Especially the color on the clothes of the frist person? In the embedded jpeg, the color is very even. In the RAW processed one it looks like the highlights are getting clipped. Nothing I do in Aperture (or LR3) seems to make it like the embedded jpeg. Any tips on how to fix this?
