Cobalt
General Information about Cobalt (#0B46A9)
The hex color #0B46A9, commonly known as Cobalt, is a deep shade of blue often associated with sophistication, trust, and stability. In the RGB color model, it is composed of 4.31% red, 27.45% green, and 66.27% blue. Cobalt blue historically derives its name from the mineral cobaltite, which was used to create blue pigments. In color psychology, blue is often linked to feelings of calmness, security, and intelligence. In web design and graphic arts, Cobalt can be effectively used to create a sense of depth, professionalism, or elegance. However, it's crucial to ensure sufficient contrast with text and other design elements to maintain readability and accessibility, especially for users with visual impairments.
The hex color #0B46A9, also known as Cobalt, presents several accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with text and other interactive elements. To ensure readability, it's crucial to use a light-colored text on a Cobalt background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. For example, white text (#FFFFFF) would be a suitable choice. Conversely, using dark text colors or other dark interface elements against a Cobalt background could result in poor readability, especially for users with visual impairments. Furthermore, it's important to avoid using Cobalt as the sole means to convey information, such as in links or buttons, as colorblind users may not be able to distinguish it effectively. Providing additional cues, like underlines or labels, is essential for inclusivity and accessibility.
