The hex color #2E47D1, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of approximately 11% means that text rendered in this color on a white background may not provide sufficient contrast for comfortable reading. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color may fall short of these recommendations, potentially causing eye strain or difficulty in discerning content for some users. To improve accessibility, consider using a lighter background color or increasing the font size and weight. Providing alternative text descriptions for graphical elements using this color is also beneficial. Testing the color combination with accessibility evaluation tools is crucial to ensure compliance with accessibility standards and to provide an inclusive user experience.
