The hex color #0F3FA4, also known as Cobalt, presents some accessibility challenges, particularly in text-based contexts. Its dark hue necessitates careful consideration of contrast ratios against lighter backgrounds to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Cobalt for text, pairing it with a light color such as white (#FFFFFF) or a very light gray is essential to meet these guidelines. Using this color for purely decorative elements is generally acceptable. Tools like contrast checkers can help developers verify compliance and make informed decisions about color pairings to enhance the user experience for all individuals, regardless of their visual abilities. The color blindness can be a problem, so it is necessary to check the contrast for different types of color blindness.
