General Information

Cerulean Blue, represented by the hex code #2E52BC, is a captivating shade of blue that evokes feelings of tranquility and clarity. This color is often associated with the sky and the sea, bringing a sense of openness and serenity. In color psychology, blue is known to promote feelings of calmness, trust, and stability, making Cerulean Blue a popular choice for branding and design projects aiming to convey these attributes. Its unique hue makes it a versatile color, suitable for a wide range of applications from digital interfaces to interior decor.

The hex color #2E52BC, also known as Cerulean Blue, presents some accessibility challenges, primarily due to its moderate contrast against lighter backgrounds. When used as text, it may not meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, particularly against white or very light gray. Therefore, designers should consider using it with darker backgrounds or increasing the text size to improve readability. For interactive elements like buttons, ensure sufficient contrast for both the regular and hover states. Implementing a contrast checker is highly recommended during the design process to verify compliance with accessibility standards. Using a darker shade of blue, or a lighter shade of yellow or white for text on this background would improve accessibility. A general rule is to test your designs with users who have visual impairments to get real world feedback.
