#1C0F89

General Information about #1C0F89

The hex color code #1C0F89 represents a deep shade of ultramarine. In the RGB color model, it is composed of 11% red, 5.9% green, and 53.7% blue. This color is predominantly blue, with very little presence of red and green, resulting in a deep and saturated hue. Ultramarine is historically significant, derived from the pigment made from ground lapis lazuli stone. It has been prized for centuries for its vibrant and enduring color. In modern usage, it is associated with sophistication, depth, and formality. Its spectral data indicates a strong reflectance in the blue wavelengths, contributing to its visual perception as a deep blue.

The color #1C0F89, a deep ultramarine, presents several accessibility considerations for web developers. Its low lightness value (approximately 6%) results in very low contrast against a standard white background. This severely impacts readability for users, especially those with visual impairments. To meet WCAG (Web Content Accessibility Guidelines) standards, it's crucial to pair this color with a very light foreground color to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using a color contrast checker is highly recommended. Furthermore, avoid using this color as the sole indicator of important information (e.g., in form fields or error messages). Supplement with text labels or icons to ensure accessibility for colorblind users. Consider offering alternative color schemes to accommodate user preferences and needs. This deep blue can be used for decorative elements where the contrast is less important.
