The color #1A3F4D, also known as Nile Blue, presents some accessibility challenges, especially when used for text. Its relatively low luminance value means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, text should have a contrast ratio of at least 4.5:1 against its background for normal text and 3:1 for large text. When using #1A3F4D for text, it's essential to pair it with a very light background color to meet these standards. Otherwise, it is advisable to reserve the color for decorative elements where readability is less critical. Tools for checking color contrast are widely available and should be a standard part of the design workflow when using this color. Using this color in combination with a slightly lighter tint of itself can cause readability issues.
