Cerulean Blue
General Information
Cerulean Blue, represented by the hexadecimal color code #2943D4, is a vibrant and captivating shade of blue that evokes a sense of calmness, depth, and clarity. It is often associated with the sky and the ocean, making it a popular choice in various design contexts. The color's name is derived from the Latin word "caeruleus," which means "sky blue" or "azure." Cerulean Blue lies within the blue color spectrum, combining elements of both cyan and a deeper, more saturated blue. In color theory, it is considered a cool color, known for its ability to create a serene and tranquil atmosphere. Its unique properties make it a valuable tool for designers seeking to convey a sense of peace, trust, and reliability. Because of its strong visual presence, it's best used sparingly in designs.
The hex color #2943D4, also known as Cerulean Blue, presents some accessibility challenges, especially when used as a background color for text. Due to its relatively low lightness value, text rendered in black or dark grays will likely fail contrast ratio tests. To ensure readability, it's crucial to pair this color with lighter text colors such as white (#FFFFFF) or very light shades of yellow or gray. Tools like the WebAIM Contrast Checker can assist in verifying that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Careful consideration of color combinations is essential to provide an inclusive user experience for individuals with visual impairments.
