The hex color #235bc3, also known as Cerulean Blue, presents some accessibility challenges, particularly when used as a background or text color. Its relatively low luminance value of approximately 21% means that it requires careful consideration of contrast ratios to ensure readability and usability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. When pairing #235bc3 with text, a light color such as white (#ffffff) or a very pale yellow would be necessary to meet these guidelines. Similarly, if #235bc3 is used as a background, text should be a light color. Using darker text colors, such as black or dark grays, could result in insufficient contrast, making the text difficult to read for users, especially those with visual impairments. Tools such as contrast checkers can assist in determining whether the contrast ratio is adequate.
