The hex color #2B21F7, a vibrant blue, presents some accessibility challenges in web design. Its contrast ratio against white text is relatively low, potentially failing WCAG standards for readability. To ensure accessibility, consider using this color with light text only for larger font sizes (18pt or 14pt bold) or as a decorative element. When using it as a background, pair it with a very light foreground color, such as white or a very pale yellow, to improve contrast. Tools like WebAIM's contrast checker can help evaluate color combinations. Also, be mindful of users with visual impairments or color blindness, providing alternative cues like icons or text labels alongside color to convey information. Ensure the website is still functional and understandable even if the color is not perceived accurately.
