In terms of light and shadow, Cello leans towards the darker end of the spectrum, possessing a relatively low luminance value.

The color #283C55, also known as Cello, presents some accessibility challenges, particularly when used for text or interactive elements. Its relatively low luminance contrast against both white and black backgrounds means that users with visual impairments may struggle to distinguish text or discern interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Cello often falls short of these recommendations, necessitating careful consideration of color pairings. To improve accessibility, it's advisable to pair Cello with lighter colors that provide sufficient contrast. For instance, using a light yellow, pale orange or a bright white for text against a Cello background can significantly enhance readability. Additionally, consider using larger font sizes or adding visual cues, such as underlines or icons, to improve the visibility of interactive elements. Always test color combinations with accessibility evaluation tools to ensure compliance with accessibility standards and to provide an inclusive user experience.
