Cerulean Blue

#254DB1

General Information

Cerulean Blue, represented by the hexadecimal color code #254DB1, is a captivating shade of blue that sits between azure and deep sky blue on the color spectrum. It evokes a sense of calmness and serenity, often associated with clear skies and tranquil seas. The color's name, 'Cerulean,' is derived from the Latin word 'caeruleus,' meaning 'dark blue' or 'sky blue.' In color psychology, Cerulean Blue is often linked to feelings of peace, tranquility, and trust. This makes it a popular choice in branding and design for businesses that wish to convey a sense of reliability and stability. It's frequently used in technology, finance, and healthcare industries to project a professional and trustworthy image.

The hex color #254DB1, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white text is approximately 4.8:1, which meets WCAG AA standards for normal text but falls short for large text (at least 18pt or 14pt bold) and graphical user interface components. When used as a background, pairing it with light-colored text, such as white or very light yellows, is recommended to ensure sufficient contrast. For users with low vision, consider providing options to adjust the color scheme or increase text size. Avoid using this color as the sole indicator for interactive elements like links or buttons; supplement it with additional cues such as underlines or borders to enhance usability for all users, including those with color vision deficiencies. Thorough testing with accessibility tools is crucial to validate the color's usability in various contexts.
