What is the technique embodied in the denial od peter to create high dark and light contrast?

The technique embodied in Peter's denial, particularly in artistic or literary contexts, often involves the use of chiaroscuro, which emphasizes the contrast between light and dark to highlight emotional turmoil and moral conflict. This contrast can symbolize the struggle between faith and doubt, redemption and betrayal. By amplifying these contrasts, the narrative or visual representation evokes a deeper emotional response, illustrating the complexity of Peter's character and his internal conflict during the denial.
