When used as a text color, it's crucial to pair it with a light background to ensure sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.

Textures or gradients can also be combined to improve the accessibility of the color to avoid any readability issues.
