With a relatively low luminance, it may pose challenges when used as a text color on a white or light background, potentially failing WCAG contrast ratio standards. To ensure readability, it's advisable to pair it with lighter text colors such as white (#FFFFFF) or very light grays. When used as a background color, ensure that the foreground text offers sufficient contrast, possibly using a light yellow or a vibrant, contrasting hue. Proper color contrast is essential for users with visual impairments, including those with low vision or color blindness, to perceive content effectively. Additionally, avoid relying solely on color to convey information; supplement color cues with text labels or icons to provide alternative means of understanding for all users. Thoroughly testing the color combination with accessibility tools is crucial to validate its usability for a diverse audience.
