The color #21315D, also known as Biscay, presents some accessibility challenges, particularly concerning color contrast. When used as a background, it requires light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Using a color contrast checker can help determine if the contrast is sufficient. For users with visual impairments, including color blindness, relying solely on color to convey information is not advisable; instead, use text labels or icons. Considering these factors, designers and developers can create more inclusive and accessible experiences for all users. It is crucial to test the color combination with assistive technologies to guarantee optimal usability.
