It would be unusual to get a digital camera that did not present the colors correctly.
But it is easy to set some option that will cause such a condition.
You should restore the camera back to factory settings.
Sony calls it "initialize"
Look in your manuals that came with the camera for the word "initialize"
When you initialize the camera it will be reset to factory settings.
Then put the camera in "Auto" and try taking pictures to see if they improved.
If the colors are still off, I would return the camera.
