Cobalt
General Information
Cobalt, represented by the hex code #0040B6, is a deep, rich shade of blue. It is often associated with sophistication, stability, and authority. In color psychology, blue is known for its calming effects, promoting feelings of tranquility and trust. Cobalt, being a darker hue, can also evoke a sense of power and professionalism. This makes it a popular choice for corporate branding, government agencies, and educational institutions. Its name comes from the mineral cobaltite, which has been used for centuries to create blue pigments. Cobalt blue has been a staple in art, fashion, and design, appreciated for its versatility and timeless appeal. Its unique depth sets it apart from lighter blues, providing a strong visual presence without being overly aggressive.
The hex color #0040B6, also known as Cobalt, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires careful consideration of the foreground text color to ensure readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text against a background. Given its relatively dark nature, pairing #0040B6 with light colors like white (#FFFFFF) or light yellow (#FFFFE0) can help meet these contrast requirements. However, using it with other dark colors can result in insufficient contrast, making content difficult or impossible to read for users with visual impairments. Designers and developers should use contrast checking tools to verify the compliance of their color choices to ensure inclusivity.
