The color #1D019A, a deep ultramarine, presents some accessibility challenges, especially in text applications. Its low luminance necessitates careful consideration of contrast ratios. When used as text against a white background, it falls short of WCAG standards for readability, potentially causing eye strain for users, particularly those with visual impairments. To improve accessibility, it's recommended to pair it with a very light color such as a very light grey or white to achieve sufficient contrast. In user interface design, avoid using this color for critical interactive elements without proper contrast. Larger text sizes benefit somewhat, but contrast remains paramount. When used as a background, ensure foreground elements are light enough to meet accessibility guidelines. Providing alternative color themes is also advisable to accommodate user preferences.
