The hex color #051293, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its very low luminance value of 0.009 makes it difficult to read text when used as a foreground color against a white or light background. According to WCAG guidelines, this color fails all contrast ratio tests for normal text (4.5:1) and large text (3:1). To ensure accessibility, it is strongly recommended to avoid using #051293 for text or interactive elements. If this color is crucial for branding, consider pairing it with very light colors like #FFFFFF or #F0F0F0 to achieve an acceptable contrast ratio. Tools like WebAIM's Contrast Checker can assist in verifying contrast ratios and ensuring compliance with accessibility standards, creating a more inclusive user experience.
