#0B3EA9

General Information about Cobalt

Cobalt, represented by the hexadecimal color code #0B3EA9, is a deep shade of blue known for its association with trust, stability, and intelligence. It belongs to the blue color family and is often used to evoke feelings of calmness, serenity, and confidence. In color psychology, blue is associated with reliability, communication, and introspection. Cobalt is a popular choice in branding and design for companies that want to convey trustworthiness and professionalism. The color's name is derived from the German word 'kobold', meaning goblin, as miners originally associated the element cobalt with troublesome ore.

The hex color #0b3ea9, also known as Cobalt, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance of 1.82 means that it may not provide sufficient contrast when used as text against a white background. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Cobalt falls short of these recommendations, potentially making it difficult for users with low vision or color blindness to read content displayed in this color. To improve accessibility, consider pairing Cobalt with lighter colors that offer a higher contrast ratio, such as white (#ffffff), light yellow (#ffffcc), or light gray (#cccccc). Additionally, providing alternative text descriptions for images and using semantic HTML can further enhance the accessibility of web content using this color.
