This quote highlights how our perceptions are inherently influenced by our inner biases, desires, and preconceptions. Even when we approach situations with ostensibly pure or straightforward intentions—such as conducting inspections or assessments—our internal state continues to shape our interpretation of what we observe. The metaphor of cleaning or examining 'horizontally and clearly' suggests an effort to look at things plainly, yet our personal 'colors' and 'moulds'—symbolic of our subjective filters—inevitably color our perceptions.

From a broader perspective, this reflection underscores the human tendency to project internal contexts onto external realities. Our experiences, emotions, and expectations act as lenses that distort the raw data we encounter, whether in artistry, science, or daily life. It reminds us to recognize our biases and understand that objectivity is often an aspirational goal rather than a guaranteed state. Awareness of these internal influences can foster greater humility and openness when interpreting information.

Furthermore, this quote can be applied to the process of understanding others. Each person perceives social interactions and events through their distinctive worldview, meaning mutual understanding requires acknowledgment of differing internal 'colors.' It also echoes themes in perception psychology, where the mind actively constructs reality based on internal inputs. At its core, it's a gentle admonition to continually scrutinize how our internal landscape colors our view of the world, urging us to seek clarity while remaining conscious of our subjective influences.
