The hex color #180EA6, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against light backgrounds, making text or interface elements difficult to read. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider pairing this color with very light shades of yellow, white, or gray. It is recommended to increase the font size and weight to enhance readability. Avoid using this color for essential interactive elements unless accompanied by clear visual cues and proper ARIA attributes to assist screen reader users. Testing with accessibility evaluation tools and users with visual impairments is essential to ensure compliance with accessibility standards.
