Because of its deep saturation, Ultramarine is best paired with lighter colors to ensure visual balance and avoid overwhelming designs.
The color #100F8C, a deep shade of ultramarine, presents some accessibility challenges. Its low luminance value means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. For normal text (smaller than 18pt), a contrast ratio of at least 4.5:1 is recommended, while large text (18pt and larger, or 14pt bold and larger) requires a ratio of 3:1. When using #100F8C as a text color, it's essential to pair it with a light background to meet these standards. Conversely, if used as a background color, ensure the text is a light, contrasting color to provide adequate readability. Tools are available to check contrast ratios and ensure compliance with accessibility standards. Also, avoid using color as the sole means of conveying important information.
