The hex color #223d64, also known as Cello, presents some accessibility challenges, especially when used for text. Its relatively low lightness value of 0.23 makes it difficult to achieve sufficient contrast with lighter background colors. According to WCAG guidelines, sufficient contrast is essential for readability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #223d64 for text, it's crucial to pair it with a very light color, such as white (#ffffff), to ensure adequate contrast. Tools like contrast checkers can help evaluate the contrast ratio. If achieving sufficient contrast proves difficult, consider using a lighter shade of blue or a completely different color palette. Also avoid using this color for important UI elements if sufficient contrast cannot be met. It is important to consider color blindness and simulate how this color is perceived for individuals with different types of color blindness.
