blue paint

Since the question had to specify red paint for the smell, we can assume that each color paint has its own smell. Otherwise it would have just said it smells like paint, not red paint. Therefore, blue paint would smell like blue paint, not red paint, and is not an accurate answer. A more fitting answer would probably be deoxygenated blood with lead poisoning from the red paint. Deoxygenated blood is blue, and it gets the red paint smell from the lead poisoning from the red paint, thus satisfying the terms of the original question.
