This color evokes feelings of stability, trust, and authority. In color psychology, blue is often associated with calmness, peace, and knowledge. Cobalt blue can be used to create a sense of sophistication and elegance in design, making it a popular choice for corporate branding, web design, and interior decorating.

The hex color #0749c3, a deep cobalt blue, presents some accessibility challenges, particularly for users with visual impairments. When used as a background color, sufficient contrast with foreground text is crucial. According to WCAG guidelines, 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 over this blue can help meet these guidelines. Tools are available online to check color contrast ratios. Also, avoid using this color as the sole indicator of important information. Supplement with text labels, icons, or other visual cues to ensure content is accessible to all users, including those with color blindness. Considering users with cognitive disabilities is important, too; ensure text over this color is clear and concise to make reading easier.
