The hex color #2404B0, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Its dark hue results in a low contrast ratio when paired with lighter text colors like white or yellow, making it difficult for users with visual impairments to read the content comfortably. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with low vision or color blindness. To improve accessibility, it's recommended to use a lighter shade of yellow or white for the text. Another approach is to use a lighter tint of ultramarine or other brighter colors for backgrounds, ensuring at least a 4.5:1 contrast ratio for normal text and 3:1 for large text. This enhances readability and inclusivity for all users.
