It's a popular color choice in various fields, including graphic design, web development, fashion, and interior design. The name 'cerulean' itself is derived from the Latin word 'caeruleus,' meaning 'dark blue' or 'sky-blue.' This color evokes feelings of calmness, serenity, and stability, making it a versatile option for creating visually appealing and emotionally resonant designs. Its specific hue is achieved by a combination of red, green, and blue light at specific intensities, which can be further adjusted to produce different shades and tints of cerulean blue.

The hex color #2254C4, also known as Cerulean Blue, presents several accessibility considerations for web developers. Its relatively low luminance can pose challenges for users with visual impairments, particularly when used as text color. To ensure readability, it is crucial to maintain a sufficient contrast ratio against the background color, ideally adhering to WCAG guidelines for AA or AAA compliance. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. When used for interactive elements, like buttons or links, additional cues such as underlines or icons can help users perceive the interactive nature of the element, especially for those who may have difficulty distinguishing color alone. Providing alternative text descriptions for images or graphical elements using this color can also enhance accessibility for screen reader users. Proper semantic HTML usage is also critical for assistive technologies.
