The hex color #004FB4, also known as Cobalt, presents some accessibility considerations for web developers. Its relatively low luminance can cause issues with text legibility, particularly when used as a background color. According to WCAG guidelines, sufficient contrast between text and background is crucial for users with visual impairments. To ensure accessibility, it's important to test the color combination using contrast checking tools. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. If #004FB4 is used for text, a lighter background color is necessary. Alternatively, if it is used as a background, a very light text color like white or a light shade of yellow is recommended. Careful consideration of font size and weight can also improve readability. Providing alternative high-contrast themes can greatly enhance the user experience for those with visual impairments.
