It is crucial to use this color judiciously, especially considering accessibility guidelines related to contrast ratios.

The color #0d18d9, a dark blue, presents significant accessibility challenges, particularly in text applications. Its low luminance value of 0.027 necessitates careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. Using #0d18d9 for text on a white background results in a contrast ratio that falls far below these recommendations, making it difficult for users with visual impairments to read. To improve accessibility, consider using lighter text colors such as white, yellow, or light gray in combination with #0d18d9, or use this color for larger, non-textual elements where contrast requirements are less stringent. Also, avoid using this color for important UI elements like buttons or links without sufficient contrast, as this can impede usability for many users.
