The hex color #223E5D, also known as Cello, presents some accessibility challenges. Its relatively low luminance value of 9 means that it may not provide sufficient contrast against lighter backgrounds, which is crucial for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. This color may not meet these standards when paired with white or very light gray. To improve accessibility, consider using a lighter tint of Cello or pairing it with a much lighter background color. Tools like contrast checkers can help determine if the contrast ratio meets accessibility guidelines. Also, ensure that any important information conveyed through color is also available through other means, such as text or icons.
