The color #210BA8, also known as Ultramarine, presents certain accessibility challenges, especially in web design. Its deep, saturated hue can cause readability issues when used as text on a light background, and conversely, light text on an Ultramarine background might strain the eyes due to insufficient contrast. To ensure accessibility, it's crucial to verify the contrast ratio using WCAG guidelines. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Lighter shades of yellow, white, or very light grays would be more suitable text colors. Additionally, consider providing alternative color schemes for users with visual impairments. Avoid using this color for critical information or interactive elements without proper contrast adjustments. Thoughtful application can enhance the user experience for everyone, regardless of visual ability. For interactive elements, it is important to use a different color for the focus state, to give the user a clear indication of the active element.
