Its intensity means it's more appropriate as an accent color.

The hex color #00089B, a deep ultramarine, presents significant accessibility challenges. Its extremely low lightness value (very close to black) means that it offers insufficient contrast against typical light-colored backgrounds like white or pale yellow. This lack of contrast can make text illegible and UI elements difficult to discern for users, especially those with visual impairments such as low vision or color blindness. To improve accessibility, it is imperative to pair #00089B with very light colors, ensuring a contrast ratio that meets WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). Avoid using it for critical information or interactive elements unless sufficient contrast is provided. Consider using a color contrast checker to verify compliance and explore alternative color palettes that offer better accessibility.
