Cerulean Blue, represented by the hexadecimal color code #1F4CD8, is a captivating shade of blue that evokes feelings of serenity, clarity, and expansiveness. It sits comfortably within the blue spectrum, offering a harmonious balance between coolness and vibrancy. Its name derives from the Latin word 'caeruleus,' meaning 'sky-blue' or 'sea-blue,' accurately capturing its resemblance to the clear, deep blue of a summer sky or the vastness of the ocean. In color psychology, blue is often associated with trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.

Its unique blend of depth and lightness sets it apart, making it a versatile color for various applications.

The hex color #1F4CD8, also known as Cerulean Blue, presents some accessibility challenges, particularly when used as a foreground color on a white background. Its relatively low luminance necessitates careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. Using #1F4CD8 for text on a white background may not meet these requirements, potentially making it difficult for some users to read. To improve accessibility, consider using a lighter background color or a brighter foreground color to increase the contrast ratio. Tools like WebAIM's Contrast Checker can help you assess and adjust color combinations to meet accessibility standards, ensuring a more inclusive user experience.
