The color #312829, often referred to as 'Thunder', presents some accessibility challenges, particularly concerning color contrast. When used as a background, it requires very light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. Testing combinations with tools like the WebAIM contrast checker is crucial. Designers should avoid pairing this color with mid-tone or dark shades as text over these colors might become illegible for users with visual impairments. Careful consideration of font size and weight can partially mitigate contrast issues, but selecting a sufficiently light foreground color remains paramount for optimal accessibility.
