Due to its darkness, it requires careful consideration of contrast when used with text or other visual elements to ensure readability and accessibility.

The color #312731, also known as Thunder, presents several accessibility challenges, especially in web design. Its low luminance value (approximately 5.4) means that text rendered in this color on a white or light background may lack sufficient contrast, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Thunder often falls short of these requirements when paired with lighter backgrounds. Therefore, it's crucial to use a lighter color for text or interactive elements when Thunder is used as a background, ensuring readability and usability for all users. Tools like contrast checkers can help determine if a specific color combination meets accessibility standards. The color should also be used sparingly and thoughtfully to avoid causing visual fatigue or discomfort, especially for users with sensitivity to dark colors.
