In the RGB color model, it is composed of 4.31% red, 28.24% green, and 65.88% blue. This particular combination gives it a rich, almost regal appearance. Cobalt derives its name from the German word 'kobold,' referring to underground spirits, which is fitting given its deep and mysterious quality. In color psychology, blue is often associated with calmness, intelligence, and dependability, making Cobalt a popular choice for brands and designs aiming to convey these attributes.

The hex color #0B48A8, also known as Cobalt, presents some accessibility challenges, especially when used as a background or text color. Its relatively low lightness value can result in insufficient contrast against lighter text or interface elements. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0B48A8, it's essential to pair it with a very light color like white or a pale yellow to ensure readability. Tools are available to check contrast ratios and verify compliance with accessibility standards, helping designers and developers make informed decisions to create inclusive and user-friendly experiences.
