The color #213A57, also known as Cello, presents some accessibility challenges. Its relatively low lightness value (approximately 0.17) means that text rendered in this color may lack sufficient contrast against a white or very light background, potentially failing WCAG's AA or AAA contrast ratio requirements. To ensure readability for users with visual impairments, consider using it primarily for larger text elements or graphic components, and always test its contrast ratio with the intended background. Pairing it with lighter shades of gray, beige, or even carefully chosen pastels can improve accessibility. Avoid using it for crucial interactive elements like links or buttons without a clear visual cue and sufficient contrast on hover or focus states. Furthermore, be mindful of colorblind users; ensure that critical information isn't solely conveyed through color.

Applications
Brand Identity
Cello can be used as a primary brand color for businesses aiming to project sophistication, trustworthiness, and stability. It evokes feelings of calmness and reliability, making it suitable for financial institutions, consulting firms, or technology companies. Use it sparingly to create a distinct and trustworthy brand image. It can be combined with gold or silver accents to enhance the feeling of luxury.
Web Design
In web design, Cello is well-suited for headers, navigation bars, and backgrounds, particularly when aiming for a professional and clean aesthetic. It can be used to create a sense of depth and sophistication. However, use with caution when implementing text on the background because it can be hard to read if contrast is not high enough. Use lighter colors for text when implementing #213A57 as a background.

Accent with lighter colors like cream or beige to prevent the room from feeling too dark. Using textured fabrics or natural materials can add warmth and interest to the space.
