#C9E0FE Hex Color

Deep neutrals like charcoal or dark slate provide the best readability against #c9e0fe. Because this blue is extremely unsaturated and light, it acts like a tint, allowing dark text to stand out without the harshness of a pure white background.

Generally, #c9e0fe is too pale to serve as a primary button color because it lacks the contrast needed for accessibility standards. Reserve it for backgrounds, subtle borders, or secondary elements, and use a much deeper blue for active, clickable interface components.
