The color #2804B0, also known as Blue Gem, presents accessibility challenges due to its dark hue. When used as a background color, it requires very light text (ideally white or a very pale yellow) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Blue Gem might fail these standards with moderately dark text colors. Using tools like a contrast checker is highly recommended to verify compliance. Furthermore, consider users with visual impairments, who may struggle to differentiate between closely-shaded colors. Avoid using this color for essential information without proper contrast adjustments. For interactive elements, ensure sufficient visual cues beyond color to accommodate colorblind users. A lighter tint of blue or the addition of borders can significantly improve usability.
