Its high blue content gives it a cool, calming effect, while its saturation ensures it remains a visually striking color.

The color #1904B0, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio is quite low, making it difficult for users with visual impairments to read. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text to meet AA standards. Ultramarine falls short of these recommendations. To improve accessibility, consider using lighter text on an Ultramarine background or using Ultramarine text on a much lighter background. Also, avoid using this color for important UI elements or interactive components without careful consideration of its contrast with surrounding colors. Providing alternative color schemes can also enhance the user experience for individuals with varying visual needs. Testing with accessibility tools is essential to ensure compliance.
