The color #121589, also known as Ultramarine, presents significant accessibility challenges, particularly in text applications. Its dark hue results in very low contrast against standard white backgrounds, failing WCAG standards for both AA and AAA levels. This means users with visual impairments, including those with low vision or color blindness, may struggle to read text rendered in this color. To improve accessibility, consider using #121589 sparingly, especially for crucial information. When using it, ensure a high contrast ratio by pairing it with very light colors, such as whites or pale yellows. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility guidelines. Also, avoid relying solely on color to convey important information; use text labels or symbols as alternatives.
