Its relatively dark hue necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text.

Consider using colorblindness simulators during the design process to preview how the color scheme appears to individuals with different types of color vision deficiencies. Thoughtful use of color enhances inclusivity and overall user experience.
