The color #304BE8, a shade of Royal Blue, presents some accessibility challenges. Its luminance value is relatively low, which means that text rendered in this color on a white background might not provide sufficient contrast for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #304BE8 for text, it's crucial to ensure adequate contrast with the background color. A lighter background color should be avoided. Using a white or very light background would fail the contrast ratio test. A darker background would improve readability for users with low vision. Tools are available online that can help designers check contrast ratios and ensure their designs are accessible to all users. Also, designers should offer alternative color themes to allow users to adjust the color scheme based on their preferences.
