This translates to a color that is predominantly blue, with very little red or green influence. The color falls into the blue-violet spectrum.

The color #000698, a deep ultramarine, presents significant accessibility challenges, particularly in web design. Its low luminance value (very dark) necessitates careful consideration of color contrast. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Avoid pairing it with other dark colors, as this will make content illegible for users with visual impairments. When used as a background, ensure that text and interactive elements are sufficiently bright. It's crucial to test the color combination with accessibility evaluation tools to ensure compliance and provide an inclusive user experience for individuals with disabilities.
