Its versatility makes it suitable for both digital and print media, where it can contribute to a visually appealing and harmonious aesthetic. In the world of color psychology, blues are often associated with stability and confidence.

The hex color #2A5CBC, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its contrast ratio against white (#FFFFFF) is approximately 3.77:1, which does not meet the WCAG AA standard for normal text (4.5:1) or large text (3:1). Therefore, using #2A5CBC directly on a white background might pose readability issues for users, especially those with visual impairments. To improve accessibility, developers should either darken the color or use a lighter text color, such as white or a very light gray, to ensure sufficient contrast. Additionally, providing alternative text descriptions for any images or graphical elements using this color is crucial. For interactive elements, ensure that the color difference provides enough visual cue for focus states, such as hover or active states, to meet WCAG 2.0 guidelines. This is even more important when color is the only mean to deliver the information. Consider using other visual indicators in addition to color.
