I said, 'Ooh, Dad, I want the yellow ones.' He said, 'Where?' I said, 'Right there, Dad. I want the yellow ones.' Everybody goes, 'Those are green'. That's how I knew I was colorblind.

Michael Rosenbaum’s quote, "I said, 'Ooh, Dad, I want the yellow ones.' He said, 'Where?' I said, 'Right there, Dad. I want the yellow ones.' Everybody goes, 'Those are green'. That's how I knew I was colorblind," humorously describes the moment he realized he was colorblind. The quote illustrates a childhood experience where Rosenbaum's perception of color was challenged by others around him. His confusion about the color of the objects he was referring to—believing they were yellow when they were actually green—marked the point at which he became aware of his colorblindness, highlighting the way this condition affected his view of the world.

The origin of this quote comes from Rosenbaum’s personal experience, where his colorblindness became apparent through a simple interaction with his father. The humor in the quote is evident as Rosenbaum recounts how everyone else was able to identify the colors correctly, but he could not, which made him realize that his perception of color was different from those around him. This moment of realization is often an amusing and memorable one for people with colorblindness, as they discover that their sense of color is not the same as that of others.

By saying, "That's how I knew I was colorblind," Rosenbaum emphasizes the unexpected and somewhat comical way in which he learned about his condition. Rather than a formal diagnosis, it was an everyday situation that led him to this discovery, making the realization both relatable and lighthearted. The quote reflects the innocence of childhood and the kind of self-discovery that can happen in simple, everyday moments.

In essence, Rosenbaum’s quote highlights the awkwardness and humor that often accompanies the discovery of a condition like colorblindness. The quote underscores how something as simple as color can be perceived very differently by those affected by it. It also speaks to the broader theme of how we come to understand our own limitations or differences through everyday interactions, often with a mix of humor and surprise.
