The hex color #0A4A6E, also known as Regal Blue, presents some accessibility challenges, especially in text-based contexts. Its low luminance of approximately 6% means it offers weak contrast against both black and white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Regal Blue fails to meet these ratios with either background, rendering text potentially unreadable for users with visual impairments. To improve accessibility, consider using a much lighter color for text on a Regal Blue background, or conversely, using Regal Blue as a background for very light text. Adjustments to font weight and size can also partially mitigate the contrast issue, but ultimately a significant luminance difference is necessary to ensure readability and meet accessibility standards.
