It is a blend of blue with slight hints of green, reminiscent of the clear sky or the deep ocean. In color psychology, blue is often associated with trust, intelligence, and confidence, making Cerulean Blue a popular choice for branding, web design, and interior decor.

This color is very versatile and can be used in various design contexts to create a calming yet sophisticated ambiance. Its balanced and harmonious nature makes it a visually appealing color choice.

The hex color #2B4EBB, also known as Cerulean Blue, presents moderate accessibility challenges. Its luminance value may not provide sufficient contrast against both black and white backgrounds, especially for users with visual impairments. When using this color for text, it's crucial to ensure a contrast ratio of at least 4.5:1 against the background color, as recommended by WCAG guidelines. Larger text sizes (14pt bold or 18pt regular) can meet the minimum contrast ratio at 3:1. To improve accessibility, consider using a lighter shade of blue or pairing it with a darker background to enhance readability. Additionally, avoid relying solely on color to convey important information, as colorblind users may not be able to differentiate it effectively. Supplement color cues with text labels, icons, or patterns to ensure inclusivity.
