Cerulean Blue

General Information about Cerulean Blue

Cerulean Blue, represented by the hexadecimal color code #3155B5, is a captivating shade of blue characterized by its vibrant and slightly desaturated appearance. It lies within the blue spectrum, exhibiting a harmonious balance between depth and brightness. This color often evokes feelings of calmness, serenity, and stability, making it a popular choice across various design disciplines. Historically, cerulean blue pigment was derived from cobalt stannate, a chemical compound known for its remarkable colorfastness and stability. In the realm of color theory, cerulean blue is considered a tertiary color, resulting from a blend of primary blue and secondary green hues. Its versatility stems from its ability to complement a wide range of other colors, making it a valuable asset in creating visually appealing and balanced designs.

The hex color #3155B5, also known as Cerulean Blue, presents moderate accessibility challenges. When used as text on a white background, the contrast ratio is approximately 3.6:1, which falls short of the WCAG AA standard requiring a 4.5:1 ratio for normal text. This means some users, particularly those with moderate visual impairments, might find it difficult to read. To improve accessibility, consider using this color for larger text sizes, where the contrast requirements are slightly less stringent (3:1 for WCAG AA). Alternatively, pair it with a lighter background color or use a darker shade of blue for the text to enhance contrast. When used for interactive elements like buttons, ensure sufficient visual cues beyond color alone are provided, such as text labels or icons, to meet accessibility guidelines for users with color blindness.
