Its rich, deep tone makes it an excellent choice for creating focal points or adding depth to visual compositions.

The hex color #0f3fa5, also known as Cobalt, presents some accessibility challenges. Its relatively low luminance of 12% means that text rendered in this color against a white background would likely fail WCAG AA and AAA contrast ratio guidelines. To ensure readability, consider using a light text color such as white (#ffffff) or a very light gray. Conversely, when using #0f3fa5 as a background, opt for light-colored text to improve contrast. It's crucial to assess the color contrast using accessibility tools to verify compliance with WCAG standards, ensuring that content is perceivable for users with visual impairments. Additionally, avoid relying solely on color to convey important information, as this can exclude users who are colorblind. Use supplementary cues such as text labels or icons to enhance accessibility.
