General Information about Cerulean Blue
Cerulean blue, represented by the hex code #2B57C9, is a captivating shade of blue that falls between azure and sky blue. It is named after cerulean, a naturally occurring pigment derived from strontium copper phyllosilicate. This color is often associated with the sky, the sea, and feelings of serenity and tranquility. In color psychology, blue is frequently linked to trust, stability, and intelligence, making cerulean blue a popular choice for branding and visual communication. Its specific hue gives it a slightly more vibrant and modern feel compared to traditional blues, making it versatile for various applications in art, design, and fashion. Cerulean blue is created by mixing primary blue with a hint of green and white, resulting in a balanced and appealing color.
The hex color #2B57C9, also known as Cerulean Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires a light text color to ensure readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. A contrast checker tool is highly recommended to verify sufficient contrast. This color might not be suitable for conveying critical information if used with similar-toned colors. Careful consideration of font size, weight, and spacing can help mitigate some of these issues. Designers should also consider providing alternative color schemes for users with visual impairments.
