Ultramarine possesses a unique spectral fingerprint, absorbing most wavelengths of light except those in the blue region, which it reflects back to our eyes, giving it its characteristic color.

The hex color #180098, also known as Ultramarine, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Ultramarine, being a dark color, may not meet these ratios with moderately light colors. Therefore, careful consideration is needed when choosing text colors to pair with it. In cases where achieving sufficient contrast is difficult, it's advisable to use a lighter tint of Ultramarine or a completely different, lighter color altogether. Additionally, relying solely on color to convey important information should be avoided. Providing alternative cues, such as text labels or icons, can ensure that content remains accessible to users with color vision deficiencies.
