The color #1A3A5E, also known as Cello, presents some accessibility challenges. Its relatively low luminance value of approximately 0.04 makes it difficult to provide sufficient contrast against light 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. Using #1A3A5E for text on a white background would likely fail these contrast tests. To improve accessibility, consider using a lighter shade of the same color family or pairing it with a much lighter accent color. Ensure that interactive elements like buttons and links have a clear visual indication when focused or hovered over. For individuals with visual impairments, providing alternative text descriptions for images and other non-text content is crucial. Careful consideration of color combinations and contrast ratios is essential to make web content accessible to all users.
