A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Failure to meet these ratios can make content difficult to read for users with visual impairments.

Consider using a lighter text color to improve readability, or employing a darker shade if Blue Dianne is used as a foreground element on a light background. Thoughtful color choices enhance the user experience for everyone, including those with disabilities.
