Cobalt is often associated with feelings of trust, stability, and intelligence, making it a popular choice for branding and design. In color theory, Cobalt is considered a cool color, evoking a sense of calmness and serenity.

The color #0247C8, also known as Cobalt, presents some accessibility challenges. Its low luminance of 12 makes it difficult to read text against a white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Cobalt falls short, requiring careful consideration. To improve accessibility, using this color for text is not recommended. Instead, pair it with a lighter color for the background, such as white (#FFFFFF) or a very light gray, to meet the contrast requirements. Alternatively, consider using Cobalt for larger elements like icons or graphical accents, ensuring that critical information isn't solely conveyed through color. Always test your color combinations with accessibility tools to ensure compliance and a positive user experience for all users.
