The color #0B48A5, also known as Cobalt, presents some accessibility challenges. Its dark hue means that it requires light-colored text for sufficient contrast, ensuring readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Cobalt as a background, careful consideration must be given to the text color choice to meet these standards.
