This can be achieved by pairing it with lighter text colors such as white (#FFFFFF) or very light yellows. Additionally, avoid using this color as the sole means of conveying important information. Supplement it with text labels or icons to ensure that users who cannot distinguish the color are still able to understand the content. Proper use enhances inclusivity.
