The hex color #2943D3, also known as Cerulean Blue, presents moderate accessibility challenges. Its luminance value of 0.122 is relatively low, meaning that text using this color as a background should ideally be paired with white or very light text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #2943D3 with dark text would likely fail these criteria, making it difficult for users with visual impairments to read comfortably. To improve accessibility, consider using a lighter shade of blue or employing a contrast checker to ensure adequate readability for all users. Implementing text shadows or borders can also enhance the legibility of text against this background color. Also be mindful of users with color vision deficiencies as they may perceive colors differently.
