The color #2D57B9, a shade of cerulean blue, presents moderate accessibility challenges. Its contrast ratio with pure white (#FFFFFF) is approximately 3.6:1, falling short of the WCAG's minimum recommendation of 4.5:1 for normal text. Consequently, using #2D57B9 for text on a white background might be difficult for users with moderate visual impairments. To enhance accessibility, consider using a lighter background color or a darker shade of blue for the text. For larger text (14pt bold or 18pt regular), the contrast ratio requirement is lowered to 3:1, which #2D57B9 nearly meets. Therefore, it could be acceptable for headings or other prominent textual elements. When used as a background color, ensure that the foreground text provides sufficient contrast. Tools like contrast checkers can help evaluate color combinations and ensure compliance with accessibility standards, promoting inclusivity for all users.
