Its name is originated from the Latin 'ultramarinus', literally 'beyond the sea', as the pigment was imported from Asia by sea.

The color #000998, a deep ultramarine, presents considerable accessibility challenges. Its low luminance value means it offers very little contrast against light backgrounds, making text or interactive elements difficult to discern for users with visual impairments. According to WCAG guidelines, it would fail most contrast ratio tests against standard white backgrounds, requiring careful consideration for foreground colors. To ensure accessibility, it's crucial to pair this color with significantly lighter shades, such as yellows or whites, to achieve a sufficient contrast ratio (at least 4.5:1 for normal text and 3:1 for large text). Avoid using #000998 for essential UI components or informative text without a high-contrast pairing. Providing alternative color schemes or allowing user customization can further improve accessibility for individuals with specific visual needs. Also consider that colorblind users may perceive this color differently, so test designs with simulations for various types of colorblindness.
