The hex color #28385A, also known as Cello, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of approximately 15% means that text rendered in this color may not provide sufficient contrast against a white or light-colored background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To ensure accessibility, consider using #28385A primarily for decorative elements or backgrounds, and always pair it with text colors that offer high contrast, such as white or a very light gray. Tools are available online to check the contrast ratio between different color combinations. Proper use of ARIA attributes and semantic HTML can further enhance accessibility for assistive technologies.
