It's interesting you mentioned the idea that the color 'red' adds 'life' to this composition. I agree with you that that is true in this particular photograph, but just today, I remember bypassing a restaurant that has good food because inside it was painted red all around and seemed a bit too austere. Furthermore, the owners have a similar attitude. Once again, the food here is excellent but the atmosphere seems too foreboding. As I proved to myself: "Man doesn't just live by bread alone." Interestingly enough in some Jewish mystic texts, the color "red" equates with 'judgement.'
