Cerulean Blue
General Information about Cerulean Blue
Cerulean Blue, represented by the hex code #1F51B7, is a captivating shade of blue located within the cyan-blue hue range. It derives its name from the Latin word "caeruleus," meaning dark blue. This color evokes feelings of calmness, serenity, and stability, making it a popular choice in various design fields. Cerulean Blue is characterized by its moderate saturation and medium brightness, allowing it to stand out without being overwhelmingly vibrant. In the RGB color model, it consists of 12.2% red, 31.8% green, and 71.8% blue. It is often associated with the sky and sea, contributing to its calming and peaceful connotations. This versatile color can be effectively used in graphic design, web development, fashion, and interior decoration to convey a sense of professionalism and tranquility.
The hex color #1F51B7, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance (brightness) means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Using #1F51B7 for text on a white background may not meet these standards. Therefore, it's crucial to pair this color with lighter backgrounds or use it sparingly for decorative elements rather than primary text. When using #1F51B7, consider increasing the font size and weight to improve readability. Testing with accessibility tools is essential to ensure compliance and provide an inclusive experience for all users. Alternative color combinations, such as pairing #1F51B7 with very light grays or off-whites, can significantly improve contrast and accessibility.
