The top photo is the Food Network's view of their Tagliatelle with Corn and Cherry Tomatoes recipe. I'm not sure what the blue cast is doing for this image. I'm assuming they were using a white plate, if so the cast is quite noticeable. It increases the overall contrast at the detriment of the warm colors of the corn, tomatoes and pasta. See how the pasta in the top photo looks gray.
I could see if this were part of a scene where the plates were on a table in open shade with a bright, sunlight lit background. Here I don't understand the reason for the blue.
