The color #280F8B, also known as Blue Gem, presents significant accessibility challenges, especially concerning color contrast. When used as text against a white background, the contrast ratio is low, making it difficult for users with visual impairments to read. Similarly, using it as a background color with light text can strain the eyes. Web developers should carefully evaluate the contrast ratio using tools like WebAIM's Contrast Checker to ensure it meets WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, consider using lighter shades of blue or pairing it with complementary colors that provide better contrast. Additionally, providing alternative text descriptions for images and using ARIA attributes can enhance the user experience for individuals using assistive technologies.
