Cobalt
General Information about Cobalt
Cobalt, represented by the hexadecimal color code #023CB2, is a deep shade of blue with strong associations to sophistication, stability, and trustworthiness. Its intense hue makes it a popular choice in various design applications. The color's name is derived from the German word 'kobalt,' originally given to a dark blue pigment used in glassmaking. This pigment was made from cobalt(II) oxide. Historically, cobalt blue was highly valued for its vibrant and lasting color. In the RGB color model, #023CB2 consists of 0.8% red, 23.5% green, and 70.6% blue. In the CMYK color model, it is composed of 99% cyan, 67% magenta, 0% yellow, and 29% black. Cobalt blue is often used to evoke feelings of serenity and competence, making it suitable for corporate branding, educational materials, and artistic endeavors.
The hex color #023CB2, also known as Cobalt, presents several accessibility considerations for web developers. Its dark hue necessitates careful selection of foreground text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against the background color. White or light yellow text would generally be suitable choices to achieve this contrast. When using this color for interactive elements like buttons or links, it is essential to provide clear visual cues, such as changes in color or state upon hover or focus, to aid users with visual impairments. Furthermore, it's vital to avoid relying solely on color to convey information, as this excludes colorblind users. Supplementary indicators, such as text labels or icons, should be included to enhance accessibility for all users.
