The color #0142C9 (Cobalt) presents some accessibility challenges, particularly regarding color contrast. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given its relatively dark nature, #0142C9 will likely need to be paired with a very light background color, such as white or a pale yellow, to meet these standards. When used for non-text elements, a contrast ratio of 3:1 with adjacent colors is recommended. Furthermore, consider providing alternative visual cues for users who may have difficulty distinguishing colors. For example, using icons or text labels in addition to color can enhance accessibility. When using it for interactive elements, ensure that hover and focus states are clearly distinguishable to aid keyboard navigation and usability for users with visual impairments. Proper attention to these aspects will improve the inclusivity of designs incorporating #0142C9.
