General Information about Cobalt

Cobalt, represented by the hex code #0147C9, is a deep and vibrant shade of blue. This color is often associated with qualities such as stability, trust, intelligence, and efficiency. In color psychology, blue is known to evoke feelings of calmness and serenity. Cobalt specifically brings a sense of authority and reliability. This makes it a popular choice for branding and marketing materials, particularly within the corporate sector. It is worth noting that the color's name, Cobalt, is derived from the German word "kobold", which means "goblin." Historically, this term was used by miners to describe ores that were difficult to refine and believed to be cursed. Cobalt as a pigment has been used for centuries, appearing in various forms of art and decorative objects.

The color #0147C9, also known as Cobalt, presents several accessibility considerations for web developers. Its low lightness value (around 15%) means that it requires careful attention to contrast ratios, especially when used for text or interactive elements. According to WCAG guidelines, text should have a contrast ratio of at least 4.5:1 against its background for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. When using Cobalt, it's crucial to pair it with very light colors such as white (#FFFFFF) or very light grays to ensure sufficient contrast. Avoid using it with colors of similar darkness levels as this will render text illegible for many users, including those with visual impairments. Additionally, consider providing alternative visual cues besides color to convey information to users who may be colorblind.
