The color #223F57, also known as Cello, is a dark, muted shade of blue-gray. It belongs to the family of cool colors and evokes feelings of calmness, stability, and sophistication. In color psychology, dark blues are often associated with trust, intelligence, and authority. This makes Cello a popular choice for corporate branding and professional websites. The color has a relatively low saturation, which contributes to its understated elegance. It is often used in designs where a subtle and refined aesthetic is desired, rather than a bold or attention-grabbing effect.

Its hexadecimal value is composed of 22 red, 3F green, and 57 blue.

The color #223F57, also known as Cello, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance can make it difficult to read against backgrounds that are not significantly lighter. According to WCAG guidelines, sufficient contrast is crucial for readability. For text, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #223F57 for text, it's important to pair it with a very light background to meet these contrast requirements. Conversely, when used as a background color, ensure that the text or other foreground elements are light enough to provide adequate contrast. Tools like contrast checkers can help verify compliance with accessibility standards, ensuring that your design is usable by individuals with visual impairments. Consideration should also be given to users with color vision deficiencies, as certain color combinations may be problematic.
