In color theory, Cerulean Blue sits between cyan and blue on the color wheel, exhibiting a strong presence and visual impact. The name 'cerulean' itself is derived from the Latin word 'caeruleus,' meaning 'dark blue' or 'sky-blue.' The color's hex code is composed of the red component '21', green component '4D', and blue component 'BF', indicating that the blue element is the most dominant. The color can be used in a wide range of applications, from web design to fashion, due to its appealing aesthetics and visual balance.
The color #214DBF, also known as Cerulean Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability, especially for users with visual impairments. A light background is essential to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Specifically, for small text, a contrast ratio of at least 4.5:1 is recommended, while for large text and graphics, a ratio of 3:1 is necessary. Using tools like contrast checkers can help determine if the color combination meets these standards, ensuring that content is accessible to a wider audience, including those with color blindness or low vision. Avoiding the use of #214DBF for critical information without sufficient contrast is highly recommended.
