Cobalt blue has a rich history, having been used in pigments and dyes for centuries.

The color #0543C5, a deep cobalt blue, presents several accessibility considerations for web development. Its low luminance value of 8 means that sufficient contrast is crucial when pairing it with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using lighter shades of yellow, white, or even lighter blues can help meet these contrast requirements. Furthermore, avoid using this color as the sole indicator for interactive elements, such as links, as users with color vision deficiencies may not be able to distinguish them. Providing additional cues like underlines or icons ensures inclusivity. When used as a background color, ensure foreground elements have adequate spacing and size for readability. Testing with accessibility evaluation tools and user feedback is crucial to guarantee a user-friendly experience for all.
