The color #0547C5, also known as Cobalt, presents some accessibility challenges, particularly in text-based applications. Due to its low lightness value, it can be difficult to achieve sufficient contrast with lighter background colors, which is crucial for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using Cobalt for text, pairing it with a very light color such as white or a pale yellow is advisable to meet these standards.

In interactive elements, ensure sufficient visual cues beyond color alone to assist users with color vision deficiencies.
