About Cerulean Blue

Cerulean Blue, represented by the hex code #2557C1, is a medium-dark shade of blue in the blue color family. It is perceived as a calming, trustworthy, and intellectual color, commonly associated with the sky, sea, and open spaces. In color psychology, blue is often linked to stability, security, and confidence, making it a popular choice for corporate branding and designs aimed at conveying reliability. The hexadecimal system defines colors using a combination of red, green, and blue values, with #2557C1 indicating specific intensities for each. Cerulean Blue sits between cyan and azure, making it a versatile shade with broad applications. Its relatively low saturation gives it a muted, refined quality.

The hex color #2557C1, also known as Cerulean Blue, presents moderate accessibility challenges. Its luminance value is relatively low, meaning it doesn't provide strong contrast against light backgrounds like white or pale yellow. When used as text, ensure a sufficient contrast ratio (at least 4.5:1 for normal text and 3:1 for large text) against its background to meet WCAG (Web Content Accessibility Guidelines) standards. Using a color contrast checker is highly recommended. Consider using this color sparingly for crucial information if sufficient contrast can't be achieved. For decorative purposes or accents, the contrast requirements are less stringent. A darker shade of blue or a complementary color used with high contrast would be better alternatives for text or important interactive elements.
