With a low luminance value, it's crucial to ensure sufficient contrast when used as text or as a background color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Using a light color like white or a bright yellow for text on a Cobalt background would greatly improve readability. Tools like contrast checkers can help verify compliance.

Also, meaningful information should not rely solely on color; supplement color cues with text labels or icons.
