The color #0C21BE, a deep Persian Blue, presents some accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 5% means that it requires very light text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. Specifically, to achieve Level AA compliance (the minimum recommended level), text using this color needs to be at least 4.5:1 contrast ratio against its background for normal text and 3:1 for large text (14pt bold or 18pt regular). For Level AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. When using this color for interactive elements like buttons or links, be sure to provide additional visual cues beyond color alone, such as underlines, borders, or icons, to ensure that users with color vision deficiencies can perceive the interactive nature of the element. Insufficient contrast can make content illegible for users with low vision or color blindness, creating a barrier to access. Therefore, choose text colors carefully and always test the contrast ratio.
