The hex color #0350B0, also known as Cobalt, presents some accessibility challenges, particularly in text applications. Due to its relatively low luminance, text rendered in this color requires careful consideration of contrast ratios. When used as a foreground color, it's crucial to pair it with a light background to ensure sufficient contrast, ideally meeting the WCAG (Web Content Accessibility Guidelines) AA standard, which mandates a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Failing to meet these ratios can render the text illegible for users with visual impairments. When used as background it's the other way around. Also avoid using this color in combination with colors that are too close in terms of luminance. Proper testing with accessibility evaluation tools is recommended to ensure compliance and optimal readability for all users. Furthermore, avoid using this color as the sole indicator of interactive elements, always provide a second hint.
