The color #1B5980, also known as Blumine, presents some accessibility challenges, primarily due to its relatively low luminance. When used as text on a white background, or vice versa, the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards for Level AA or AAA compliance. This means that users with visual impairments, such as those with low vision or color blindness, might find it difficult to read the text. To improve accessibility, consider using #1B5980 with lighter background colors to increase the contrast ratio to at least 4.5:1 for normal text and 3:1 for large text. Alternatively, using a darker text color on a #1B5980 background can also improve readability. Tools like contrast checkers can help ensure compliance with accessibility standards.
