Today, it is widely used in various applications, including art, design, and manufacturing, and has a captivating and alluring hue that makes it a popular choice for creating a sense of depth and sophistication.

The color #003AB4, also known as Cobalt, presents some accessibility challenges. Its low luminance value of approximately 5.4 cd/m² means that it requires careful consideration of contrast ratios, particularly when used as a background color for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text against its background to ensure readability for users with moderate visual impairments. For large text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Given its dark nature, pairing #003AB4 with light colors like white (#FFFFFF) or very pale yellows and greens will provide sufficient contrast. However, using it with similar dark shades of blue, purple, or black should be avoided, as it would render the text or elements illegible for many users, especially those with low vision or color blindness. Proper testing with accessibility evaluation tools is crucial to ensure compliance and optimal user experience. Designers should also consider providing alternative color schemes to cater to individual user preferences and needs.
