The hex color #183A56, also known as Nile Blue, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance value of approximately 0.042 means that it requires a high contrast ratio with text to ensure readability, particularly for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When pairing #183A56 with text, it's crucial to use light colors like white or very pale shades of yellow or gray to meet these contrast requirements. Tools like contrast checkers can assist in verifying that the chosen color combination provides sufficient contrast. Consider the font size and weight as well, as thicker fonts may improve readability at lower contrast ratios. To avoid accessibility issues, avoid combining Nile Blue with darker shades of blue, green, or black for text or interactive elements.
