The color #280B8D, also known as Blue Gem, presents some accessibility challenges. Its dark nature results in low contrast against white backgrounds, which can make text difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for readability. To improve accessibility, consider using a lighter text color such as white or a very light gray. Alternatively, if #280B8D is used as a background, ensure that the foreground text is a light color to meet the contrast ratio requirements. Also avoid using this color for essential UI elements like buttons or links without proper contrast, as it could lead to usability issues. When in doubt, always test the color combination with accessibility evaluation tools to ensure compliance.
