The hex color #004378, also known as Regal Blue, presents some accessibility challenges, particularly in text-based applications. Its low luminance value requires careful consideration of color contrast ratios. When used as a background color, it necessitates light-colored text (white or very pale shades) to ensure readability, adhering to WCAG (Web Content Accessibility Guidelines) standards. Conversely, if used for text, a very light or white background is crucial. Failure to meet contrast ratio minimums can result in content that is difficult or impossible for users with visual impairments to perceive, including those with low vision or color blindness. The use of tools that check color contrast ratios is highly recommended during the design and development process to ensure compliance and inclusivity.
