The hex color #003BB4, also known as Cobalt, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it is crucial to ensure sufficient contrast against the 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. Given the darkness of Cobalt, it requires a very light background color (like white, #FFFFFF or a very light yellow, #FFFFE0) to meet these standards. Using darker backgrounds can render the text unreadable for users with visual impairments. For interactive elements like buttons, providing clear visual cues beyond color alone is advisable. Consider using borders, icons, or text labels to ensure usability for all users. Thorough testing with color contrast tools is highly recommended to ensure compliance with accessibility standards.
