This combination creates a unique blue hue that is widely used in various design applications. Cerulean Blue's popularity stems from its ability to convey both tranquility and sophistication. Its name is derived from the Latin word 'caeruleus', meaning 'dark blue', further emphasizing its connection to the natural world and its enduring appeal across different cultures and artistic movements. Its specific blend of red, green, and blue components gives it a distinct visual presence that stands apart from other shades of blue.

The color #204CB6, also known as Cerulean Blue, presents some accessibility challenges, particularly regarding contrast. When using this color for text, it is crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text (14pt bold or 18pt regular). Pairing this blue with white text may fall short of these recommendations, potentially making it difficult for users with visual impairments to read. Therefore, consider using a lighter shade of blue or a darker background color to improve contrast. Alternatively, a color contrast checker tool can be used to verify adequate contrast ratios. Thoughtful color selection is paramount in web design to ensure inclusivity and optimal user experience.
