The color #1C0890, a deep ultramarine, presents accessibility challenges, especially when used as text on a white background. Its low luminance contrast ratio makes it difficult for users with visual impairments to read. To enhance accessibility, consider using a lighter color for text on this background or a lighter background for text in this color. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, and 3:1 for large text. Tools like WebAIM's contrast checker can help evaluate contrast ratios. Providing alternative text descriptions for images that use this color is also crucial for screen reader users. Ensuring sufficient spacing between elements and avoiding reliance solely on color to convey information will further improve the user experience for everyone, including those with color vision deficiencies.
