The color #183D51, a deep, muted blue, presents some accessibility considerations for web development. When used as a background color, it's crucial to ensure that the foreground text provides sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using a light text color like white or a pale yellow can help achieve this contrast. However, simply choosing a light color isn't enough; contrast checking tools should be utilized to verify compliance. If the contrast is insufficient, consider lightening the color #183D51 or using a darker text color. For interactive elements like buttons and links, ensure that there is a distinct visual cue beyond color alone to indicate their interactive state. Providing clear focus indicators and using underlines for links are great ways to enhance accessibility for users with visual impairments.
