The hex color #003BB3, also known as Cobalt, presents some accessibility challenges, particularly regarding color contrast. When using this color for text or interactive elements, it's 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, lighter colors such as white, yellow, or very light grays are advisable for text. Tools like WebAIM's contrast checker can be used to verify compliance. Avoid pairing Cobalt with other dark colors, as this will likely result in insufficient contrast, making content difficult for users with visual impairments to read and interact with. Consider providing alternative color schemes for users who may have difficulty perceiving the intended contrast.
