The color #100FA5, Ultramarine, presents some accessibility challenges, particularly regarding text contrast. When using Ultramarine as a background color, it's crucial to pair it with a light foreground color like white or a very pale yellow to ensure sufficient contrast ratio. Text rendered in black or dark shades against an Ultramarine background may be difficult for users with visual impairments to read. Adhering to WCAG guidelines for color contrast is highly recommended, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Careful consideration of color combinations can significantly improve the user experience for individuals with varying visual abilities, ensuring content is both visually appealing and accessible. Tools are available to check the contrast ratio of color combinations. Using different sizes or font weights can also improve legibility.
