The color #09128F, a deep ultramarine, presents significant accessibility challenges. Its very low luminance (darkness) results in poor contrast against common background colors like white. This makes it difficult for users with visual impairments, including those with low vision or color blindness, to read text or distinguish interface elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #09128F will likely fail these tests against light backgrounds. To improve accessibility, consider using a much lighter text color (e.g., shades of white or yellow) on this background, or lightening the color itself. Tools like contrast checkers can accurately measure the contrast ratio. Avoid using this color for critical information without ensuring sufficient contrast.
