General Information about Cerulean Blue

Cerulean Blue, represented by the hexadecimal color code #2A4ABC, is a shade of blue that lies between azure and deep sky blue. Its name originates from the Latin word "caeruleus," meaning dark blue or blue-green. This color is often associated with the sky and the sea, evoking feelings of calmness, tranquility, and stability. In color psychology, blue is known to represent trust, loyalty, and intelligence. Cerulean Blue, with its slightly muted tone, also brings a sense of sophistication and elegance. It's frequently used in design to convey trustworthiness and professionalism, making it a popular choice for corporate branding and user interfaces. The color is created by mixing red, green, and blue light at specific intensities.

The hex color #2a4abc, also known as Cerulean Blue, presents several accessibility considerations for web developers. Its luminance value is relatively low, which means it may not provide sufficient contrast when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to be able to read and interact with content effectively. A contrast ratio of at least 4.5:1 is recommended for normal text, and 3:1 for large text. When using #2a4abc, it's essential to pair it with a very light color to meet these contrast requirements. Tools are available to check color contrast ratios and ensure compliance with accessibility standards. Furthermore, avoid using this color as the sole indicator for interactive elements; supplement it with other visual cues like underlines or icons to ensure usability for all users.
