Its relatively low luminance value of approximately 10% means that text rendered in this color may lack sufficient contrast against lighter backgrounds, making it difficult to read.

When using #21417A, it's crucial to pair it with a very light color, such as white or a pale yellow, to ensure adequate contrast.

Supplement color cues with text labels or icons to enhance usability for all users. Testing with accessibility tools is recommended.
