General Information about Cobalt

Cobalt, represented by the hexadecimal color code #0742AD, is a deep shade of blue. It derives its name from the element cobalt, which is known to produce blue pigments. Cobalt is commonly associated with feelings of stability, trust, and knowledge, and is frequently used in corporate branding to convey professionalism and reliability. In art and design, Cobalt is used to create depth and dimension. It’s a color that conveys sophistication and can be found in various applications, from paint to textiles. Cobalt's relatively low lightness value makes it appear darker, and it is important to use proper contrast when using it to ensure legibility and accessibility, especially in digital environments. In history, Cobalt was used to color glass and ceramics.

The color #0742AD, also known as Cobalt, presents accessibility challenges due to its low luminance. When used as text on a white background, it may not meet the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines). This can make it difficult for users with visual impairments to read the text. Similarly, using white text on a Cobalt background can also present readability issues. To improve accessibility, consider pairing Cobalt with lighter shades of yellows, greens or lighter blues to ensure sufficient contrast. Tools such as contrast checkers can help determine if the color combination meets accessibility standards. For crucial UI elements, such as buttons, it is vital to use combinations with a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as specified by WCAG 2.1 AA. Using thicker fonts can also help to improve readability.
