The hex color #1C0E8A is not a web-safe color.

The color #1C0E8A, a deep ultramarine, presents several accessibility considerations for web development. Its low lightness value (perceived brightness) means it requires careful pairing with contrasting colors to ensure readability. When used as a text color, it demands a very light background to meet WCAG standards for contrast ratio. A lighter color like #FFFFFF (white) or a light shade of yellow or beige would work well. If #1C0E8A is used as a background color, text should be in a light hue. Using a color contrast checker is highly recommended to verify compliance with accessibility guidelines, especially WCAG 2.1 AA or AAA levels. Furthermore, avoid using #1C0E8A as the sole means of conveying information; always provide redundant cues, such as text labels or icons, to accommodate users with color vision deficiencies. Consider providing options for users to adjust color schemes to their preferences.
