The hex color #000428, often referred to as Black Russian, presents significant accessibility challenges due to its extremely dark nature. Its low luminance results in very poor contrast against lighter backgrounds, making it difficult for individuals with visual impairments to perceive text or graphical elements rendered in this color. In web design, using #000428 for text or icons on a white or light-colored background would fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure accessibility, it is crucial to avoid using this color for primary content elements unless paired with an exceptionally light color that provides a high contrast ratio (at least 4.5:1 for regular text and 3:1 for large text). Consider using lighter tints or shades or relying on alternative colors to ensure inclusivity.
