It lies between azure and sky blue, offering a slightly more muted and complex tone. The name "cerulean" is derived from the Latin word "caeruleus," which refers to the color of the sky or the sea. This color is often associated with calmness, stability, and intellectualism. In color psychology, blue is known to promote feelings of peace, trust, and security. Cerulean Blue specifically can be seen as a color of authority and professionalism, making it suitable for various applications ranging from corporate branding to creative design projects.

The hex color #274CBF, also known as Cerulean Blue, presents some accessibility challenges, especially in web design. Its luminance value is relatively low, which means that text using this color as a background or foreground might lack sufficient contrast with elements of other colors. To ensure readability and usability for all users, including those with visual impairments, it's crucial to pair this color with lighter shades for text or interface components. White (#FFFFFF) or very light grays generally work well. When using #274CBF as a background, consider employing a color contrast checker to verify that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for at least a 4.5:1 contrast ratio for normal text and 3:1 for large text. Also, avoid using this color to convey critical information without additional cues, such as icons or labels, as color alone should not be the sole indicator for essential elements.
