The color #21616E, also known as Casal, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.9:1, which is below the WCAG AA standard of 4.5:1 for normal text. This means that users with moderate visual impairments may find it difficult to read text displayed in this color on a white background. To improve accessibility, consider using a lighter background color or a darker text color to increase the contrast ratio. For larger text (14pt bold or 18pt regular), the contrast ratio passes the AA requirement. To meet AAA standards, a contrast ratio of 7:1 is needed.
