Understanding the properties and psychological associations of Cobalt can help designers effectively use it to convey specific messages and emotions.

The hex color #0B3FA8, also known as Cobalt, presents specific accessibility considerations for web development. Given its relatively dark hue, it's crucial to ensure sufficient contrast when pairing it with text or other interactive elements. A low contrast ratio can significantly hinder readability and usability, particularly for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, when using #0B3FA8 for backgrounds, foreground elements should be a light color, such as white or a very light shade of yellow or gray. Tools like contrast checkers can help verify compliance with accessibility standards. Furthermore, avoid relying solely on color to convey important information, as colorblind users may not perceive it accurately. Supplement color cues with text labels, icons, or patterns to ensure inclusivity and enhance the overall user experience.
