In the RGB color model, this translates to 24 red, 19 green, and 136 blue. This color is mostly used in situations when a bold and strong color is required. Ultramarine is a historical pigment, originally derived from the gemstone lapis lazuli.

Today, synthetic ultramarine is widely available, making it an accessible color for various applications.
The color #181388, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. A light background is generally recommended to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. For small text, a contrast ratio of at least 4.5:1 is necessary, while for larger text (14pt bold or 18pt regular) a ratio of 3:1 is required. Tools like WebAIM's contrast checker can be used to verify compliance. Avoid pairing this dark color with other dark colors, as this will severely impact readability. Consider using a lighter tint of ultramarine or a completely different, lighter color palette to improve accessibility for users with visual impairments. Providing alternative visual cues, such as icons or underlines, alongside color can also enhance usability.
