The hex color #2955BD, also known as Cerulean Blue, presents some accessibility challenges. Its contrast ratio against white is approximately 2.7:1, which falls short of the WCAG's minimum recommended contrast ratio of 4.5:1 for normal text and 3:1 for large text. This means that using #2955BD for text on a white background might be difficult for users with low vision or color vision deficiencies to read. To improve accessibility, consider using a lighter background color or darkening the text color. When used for non-text elements, the color can be more forgiving as there are generally no readability requirements. Designers should always consider the needs of all users when selecting colors, and testing with accessibility tools is highly encouraged. The use of Cerulean Blue might also benefit from being paired with labels or design elements that can help to better highlight contrast.
