The color #152A25, also known as Celtic, presents some accessibility challenges, primarily due to its low lightness value. Its darkness means that text rendered in this color requires careful consideration of contrast ratios, especially against a white or very light background. According to WCAG guidelines, sufficient contrast is essential for readability and usability. For normal text (14pt/18px and larger), a contrast ratio of at least 4.5:1 is recommended, while for large text (18pt/24px and larger), a contrast ratio of 3:1 is considered acceptable. Using #152A25 for text on a white background might not meet these guidelines, potentially causing visual strain for users, particularly those with visual impairments. To improve accessibility, consider pairing it with a much lighter foreground color, or using #152A25 sparingly for decorative elements rather than essential text. Also, providing alternatives via CSS is recommended.
