The hex color #02175B, also known as Gulf Blue, presents significant accessibility challenges, particularly in web design. Its very low luminance value means that text rendered in this color requires extremely light foreground colors to achieve sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. Using #02175B for text without careful consideration of contrast can lead to a poor user experience, especially for individuals with low vision or color blindness. Therefore, it's crucial to pair this color with very light shades or white to meet accessibility standards. Tools like contrast checkers can help determine if the chosen color combination provides adequate contrast.
