It is a popular color in corporate branding and web design due to its ability to convey a sense of professionalism and reliability. The color gets its name from the element Cobalt, which produces a similar deep blue pigment when used in paints and other materials. Cobalt is visually appealing and has a calming effect.

The hex color #003CB3, also known as Cobalt, presents moderate accessibility challenges. With a low luminance value, it requires careful consideration when used as a background or text color. For text, it's crucial to ensure a high contrast ratio against the background to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a light color like white or a very pale yellow as the text color on a Cobalt background can improve readability. For graphical elements and user interface components, ensure a contrast ratio of at least 3:1 against adjacent colors. Avoid using #003CB3 for critical interactive elements without proper contrast, as users with visual impairments may struggle to perceive them. Also, provide sufficient color-independent cues, such as text labels or icons, to ensure that users can understand the purpose of elements even if they cannot distinguish the color.
