The color #2104B0, a deep ultramarine, presents several accessibility considerations for web development. Its strong hue provides a good starting point, but careful attention must be paid to contrast ratios. When used for text, it's crucial to ensure sufficient contrast against the background to meet WCAG guidelines for readability. A light yellow or white background is highly recommended. For larger text elements, the contrast requirements are somewhat relaxed, but still important. Avoid pairing #2104B0 with very dark colors, as this will likely result in insufficient contrast. Also, consider users with color vision deficiencies; relying solely on color to convey information is discouraged. Always provide alternative cues, such as text labels or icons, to ensure content is accessible to everyone. When used in interactive elements, ensure focus states are clearly visible to aid keyboard navigation. Proper use of ARIA attributes can further enhance accessibility for assistive technologies.
