General Information about Cobalt Blue
Cobalt blue, represented by the hexadecimal color code #034A9E, is a deep and rich shade of blue that evokes feelings of sophistication, stability, and trust. It is named after the naturally occurring pigment cobalt aluminate, which has been used for centuries to color ceramics and glass. In the RGB color model, #034A9E is composed of 1.2% red, 29% green, and 62% blue. Its CMYK values are 97% cyan, 54% magenta, 0% yellow, and 38% black. This color is often associated with corporate branding, technology, and government institutions due to its connotations of reliability and authority. Its depth and complexity make it a versatile choice for various design applications, lending a touch of elegance and professionalism.
The color #034A9E, a deep shade of cobalt blue, presents some accessibility challenges. Its low luminance value of approximately 3 means that it requires careful consideration when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background to be considered accessible. When pairing #034A9E with text, a very light color like white (#FFFFFF) or a light yellow is strongly recommended to ensure sufficient contrast. Tools such as contrast checkers can assist in verifying compliance. Avoid using this color for small text or critical interactive elements against dark backgrounds. Enhancements such as text shadows or borders can improve legibility, but contrast should always be the primary consideration for accessibility.
