The color #21302E, also known as Shark, presents some accessibility challenges. Its dark nature means it has low contrast with lighter text or backgrounds. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. To ensure readability, especially for users with low vision or color blindness, it's recommended to pair this color with very light shades. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is advisable. Using tools to check color contrast ratios is a good practice. Also, avoid using this color as the sole indicator of important information, as users who are colorblind may not be able to distinguish it from other dark colors. Always provide alternative cues, such as text labels or icons.
