In the book "The Beach" by Alex Garland, a thought-provoking idea is presented through a quote about perception and the nature of comparison. The saying suggests that when one is surrounded by a uniform environment, like an all-blue world, the concept of color becomes irrelevant. It implies that without contrasting elements, the uniqueness or strangeness of things may go unnoticed.

This notion emphasizes how our understanding of the world is shaped by our experiences and the contexts in which we find ourselves. When people are isolated or immersed in a singular perspective, they may fail to question their surroundings or recognize anomalies. This reflection on human perception highlights the significance of external influences in shaping our reality and understanding of the world.
