The color #1713A1, a deep ultramarine, presents considerable accessibility challenges, especially when used as a background or text color. Its low luminance value of approximately 3% requires careful consideration of color contrast ratios to ensure readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) against a background. Given the darkness of #1713A1, pairing it with light colors, such as shades of white or yellow, is essential. Using online contrast checkers can help assess the compliance of color combinations. Furthermore, avoid using this color for essential information or interactive elements without proper contrast, as it can significantly impact users with visual impairments. Providing alternative styling options for users to customize their viewing experience can also improve accessibility.
