The hex color #0B48A0, also known as Cobalt, presents some accessibility challenges, particularly when used as a background color for text. Its relatively low luminance value (approximately 0.03) means that text rendered in black or darker shades would have very poor contrast, making it difficult to read. To ensure readability, it's crucial to pair Cobalt with a light color for text, such as white (#FFFFFF) or a very light gray. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. Tools like contrast checkers can help verify that the chosen color combination meets these standards, ensuring accessibility for users with visual impairments. Avoid using this color for small text or important interactive elements without careful consideration of contrast.
