When using #0000b4, ensure that the foreground text color is sufficiently light to meet these contrast requirements. Tools like contrast checkers can help verify compliance.

Supplement color cues with text labels or other visual indicators to enhance accessibility. Careful consideration of these factors ensures a more inclusive and user-friendly web experience.
