The hex color #040259, a deep and intense shade of blue often referred to as Gulf Blue, presents significant accessibility challenges. Its very low luminance value of 0.002 means it offers extremely poor contrast against white text, failing all WCAG contrast ratio guidelines for normal text (minimum 4.5:1) and large text (minimum 3:1). Using white text on a #040259 background is not recommended due to readability issues; the text will be extremely difficult to discern, especially for users with visual impairments. Similarly, black text on #040259 is virtually illegible. To improve accessibility, consider using much lighter shades of blue or other colors that offer a high contrast ratio. Tools like contrast checkers can help identify accessible color combinations. Avoid pairing #040259 with dark colors. If #040259 is used as a background, ensure all interactive elements and text meet minimum contrast requirements to provide a usable experience for all users. Consider using a lighter tint of the base color.
