Cobalt blue has a rich history, dating back to ancient civilizations. It has been used in pigments for centuries.

Its vibrant tone has made it a popular choice in many areas of visual and material culture.

The hex color #033CB0, also known as Cobalt, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 4% means that text rendered in this color against a white or light background will have very poor contrast, failing WCAG (Web Content Accessibility Guidelines) standards for readability. Specifically, it falls far short of the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using #033CB0 sparingly for decorative elements or pairing it with much lighter colors like white or pale yellow for text and interactive elements. Ensuring sufficient contrast is crucial for users with low vision or color blindness to perceive content effectively, promoting inclusivity and usability.
