When used effectively, Nile Blue can provide a sense of understated elegance and professional appeal, particularly when paired with complementary colors or used as an accent color against lighter backgrounds.

The color #163E4A, also known as Nile Blue, presents some accessibility challenges, particularly in text-based applications. Its dark hue results in a low contrast ratio against standard light backgrounds (like white), potentially making it difficult for users with visual impairments to read text rendered in this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Nile Blue often falls short of these recommendations when paired with light backgrounds, necessitating careful consideration. To improve accessibility, web developers should use Nile Blue sparingly for text or pair it with a sufficiently light color (e.g. white or very light grey) or use a dark color for the background to ensure a compliant contrast ratio. Tools like contrast checkers can help determine appropriate color pairings. Additionally, consider providing alternative color themes or allowing users to customize the color scheme to meet their individual needs and preferences. While Nile Blue can be effective for visual elements such as borders or decorative accents, its use should be approached cautiously with text to ensure inclusivity.
